-/**
- * Given a metric data template, and a metric data point, accumulate into the
- * aggregator.
+ * To efficiently perform the average, care is taken to reduce the number of
+ * CPU cycles required to analyze the data.  To do this, any calculation that is
+ * done on a data point (such as its time index) is stored.  This is necessary
+ * because a given data point can be considered for aggregation into any number
+ * of configured time aggregations.
  *
- * @param {Object} data
- * The metric data template received.
+ * Also, to prevent re-aggregating the data needlessly, each aggregate level
+ * maintains its position in the base array, thereby keeping track of where it
+ * left off.  This is done using two simple numbers: the last array element
+ * examined and the start of the current time band.
  *
- * @param {Object} metric
- * The metric data point received.
+ * So that data is still streamed on an event-basis, an aggregate data point is
+ * only captured and emitted when it is complete.  To detect when an aggregate
+ * is complete, the algorithm traverses the base real-time array of data, beginning
+ * where it left off for any given aggregate.  Walking each element from there
+ * forward, a simplistic level-break algorithm is implemented.  As and when a
+ * logical time index changes, this indicates that the previous set of data is
+ * complete.
  *
- * @param {Object} aggregate
- * The aggregator object.
+ * Once this occurs, the program then averages the data from the starting index
+ * through the ending index that spans a logical time unit, regardless of aggregate
+ * level (using the time index formula above).
  *
- * @returns {void}
+ * Image a set of tuples: (physical index, logical time index, value):
+ *
+ * [ 0,0,1.3 ], [ 1,0,4.5 ], [ 2,0,3.7], [3,1,4], [4,2,5.6], [5,2,0.3], [6,5,9.1]
+ *
+ * elements[0..2] have the same time index and when element[3] is encountered, a
+ * change in time index is detected.  In state variables, the program knows to re-read
+ * elements[0..2] and perform the average (shown below).  State variables update to
+ * reflect this new end point where aggregation has been completed for that aggregate
+ * level.
+ *
+ * The program continues and at the end of reading the data above, the average
+ * would be:
+ *
+ * [ 3.2, 4, 2.9 ]
+ *
+ * The final tuple would not be processed because nothing came after it.  But when it
+ * did get processed, the program would also include 0-averages for logical time
+ * elements 3 and 4.  When a gap is detected between two logical time elements,
+ * the program replaces them with averages equal to zero.
+ *
+ * To ensure no overflows (and therefore NaN) are produced, the average is done
+ * using the formula on the left-side of this equivalence:
+ *
+ *     k[0]     k[1]     k[2]           k[n]     sum([k0...kn])
+ *    ------ + ------ + ------ + ... + ------ = ---------------- = avg([k0...kn])
+ *     n - 1    n - 1    n - 1          n - 1        n - 1
+ *
+ * The sum of memory usage even over a 10s aggregate is enough to produce NaN.

Subject: [PATCH 19/21] fix(#64) memory guage view frozen

The memory guage view was not getting its "metrics" events and appears frozen.
Since it is not a historical graph, the "metrics" event needed to be emitted every time.

+# Metric Aggregation
+
+The MetricsProvider class provides metric data for various data points.
+
+The data provided is streamed in two modes:
+* Real Time
+  * A slice of the data that has been collected over time.
+* Aggregate
+  * Data that has been rolled-up to various time increments.
+
+## Time Indexes
+
+The strategy for aggregation centers around time indexes.  Imagine an array
+of values and each element of that array being a data point.  If the data
+is real-time, then each index is just one logical second.  When the data
+is aggregated, each data point is the average of the data, for one logical
+grouping of time.
+
+To determine which data elements from the real-time array are to be grouped,
+the difference in time from the start of the process and the moment a data
+point was captured is passed through this formula:
+
+<img style="margin: 0 auto; display: block;" src="./images/time-index-equation.png"></img>
+
+Where
+
+* `i`
+  * Time Index
+* `t[k]`
+  * Time of element `k`
+* `t[s]`
+  * Start time of process
+* `u`
+  * Time unit of measure (e.g. 5000ms=5s)
+
+All Times are expressed in milliseconds (ms) and are obtained from Date.now().
+
+**Example**
+
+<img style="margin: 0 auto; display: block;" src="./images/time-index-equation-example.png"></img>
+
+The above example demonstrates that for a 5000ms (5s) aggregate, the time index
+for the data point is one.  This formula is applied to all data points, so
+when many data points share the same logical time index, they can be averaged.
+When two or more array elements have a common time index, they form a time band.
+
+<img style="margin: 0 auto; display: block;" src="./images/aggregation-visual.png"></img>
+
+In the above visual, the start time `t[s]` is `7581298`.  The unit of time is `5000ms`.  By applying
+the time index equation against each data points' moment in time, the time index values are
+derived.  For those that match, a time band is formed.  These are colorized similarly.
+
+## Averaging
+
+To efficiently perform the average, care is taken to reduce the number of
+CPU cycles required to analyze the data.  To accomplish this, the program
+calculates the average inline with the originating transaction.
+
+Also, to prevent re-aggregating the data needlessly, each aggregate level
+maintains its position in the base array, thereby keeping track of where it
+left off.  This is done using two simple numbers: the last array element
+examined and the start of the current time band.
+
+So that data is still streamed on an event-basis, an aggregate data point is
+only captured and emitted when it is complete.  To detect when an aggregate
+is complete, the algorithm traverses the base real-time array of data, beginning
+where it left off for any given aggregate.  Walking each element from there
+forward, a simplistic level-break algorithm is implemented.  As and when a
+logical time index changes, this indicates that the previous set of data is
+complete.
+
+Once this occurs, the program then averages the data from the starting index
+through the ending index that spans a logical time unit, regardless of aggregate
+level (using the time index formula above).
+
+To ensure no overflows (and therefore `NaN`) are produced, the average is done
+using the formula on the left-side of this equivalence:
+
+<img style="margin: 0 auto; display: block;" src="./images/average-equivalence-equation.png"></img>
+
+The sum of memory usage even over a 10s aggregate is enough to produce `NaN`.

- * The real time data is simply a slice of the data that has been collected
- * over time.
- *
- * The aggregate data is data that has been rolled-up to various time increments.
- *
- * The strategy for aggregation centers around time indexes.  Imagine an array
- * of values and each element of that array being a data point.  If the data
- * is real-time, then each index is just one logical second.  When the data
- * is aggregated, each data point is the average of the data, for one logical
- * grouping of time.
- *
- * To determine which data elements from the real-time array are to be grouped,
- * the difference in time from the start of the process and the moment a data
- * point was captured is passed through this formula:
- *
- * Time Index = Math.floor((Data Point Time - Process Start Time) / Time Units)
- *
- * All Times are expressed in milliseconds (ms) and are obtained from Date.now().
- *
- * Example: Process Start Time 8798172749871
- *          Data Point Time    8798172756481
- *          Delta                       6610
- *          Time Units                  5000
- *          Quotient                       1.322
- *          Floor                          1
- *
- * The above example demonstrates that for a 5000ms (5s) aggregate, the time index
- * for the data point is one.  This formula is applied to all data points, so
- * when many data points share the same logical time index, they can be averaged.
- * When two or more array elements have a common time index, they form a time band.
- *
- * To efficiently perform the average, care is taken to reduce the number of
- * CPU cycles required to analyze the data.  To accomplish this, the program
- * calculates the average inline with the originating transaction.
- *
- * Also, to prevent re-aggregating the data needlessly, each aggregate level
- * maintains its position in the base array, thereby keeping track of where it
- * left off.  This is done using two simple numbers: the last array element
- * examined and the start of the current time band.
- *
- * So that data is still streamed on an event-basis, an aggregate data point is
- * only captured and emitted when it is complete.  To detect when an aggregate
- * is complete, the algorithm traverses the base real-time array of data, beginning
- * where it left off for any given aggregate.  Walking each element from there
- * forward, a simplistic level-break algorithm is implemented.  As and when a
- * logical time index changes, this indicates that the previous set of data is
- * complete.
- *
- * Once this occurs, the program then averages the data from the starting index
- * through the ending index that spans a logical time unit, regardless of aggregate
- * level (using the time index formula above).
- *
- * Image a set of tuples: (physical index, logical time index, value):
- *
- * [ 0,0,1.3 ], [ 1,0,4.5 ], [ 2,0,3.7], [3,1,4], [4,2,5.6], [5,2,0.3], [6,5,9.1]
- *
- * elements[0..2] have the same time index and when element[3] is encountered, a
- * change in time index is detected.  In state variables, the program knows to re-read
- * elements[0..2] and perform the average (shown below).  State variables update to
- * reflect this new end point where aggregation has been completed for that aggregate
- * level.
- *
- * The program continues and at the end of reading the data above, the average
- * would be:
- *
- * [ 3.2, 4, 2.9 ]
- *
- * The final tuple would not be processed because nothing came after it.  But when it
- * did get processed, the program would also include 0-averages for logical time
- * elements 3 and 4.  When a gap is detected between two logical time elements,
- * the program replaces them with averages equal to zero.
- *
- * To ensure no overflows (and therefore NaN) are produced, the average is done
- * using the formula on the left-side of this equivalence:
- *
- *     k[0]     k[1]     k[2]           k[n - 1]     sum([k0...kn-1])
- *    ------ + ------ + ------ + ... + ---------- = ---------------- = avg([k0...kn-1])
- *      n        n        n                n               n
- *
- * The sum of memory usage even over a 10s aggregate is enough to produce NaN.
