Overview

This PR adds execution timing information to long-running test suites.

It adds three kinds of information to test output:

1. The CPU time required to execute each individual test (in milliseconds):

   prop_makeChangeForUserSpecifiedAsset_sum (189ms)
       +++ OK, passed 1000 tests.
   prop_makeChangeForUserSpecifiedAsset_length (179ms)
       +++ OK, passed 1000 tests.

2. The total CPU time required to execute the entire test suite:

   Finished in 5.8572 seconds, used 18.3714 seconds of CPU time
   33 examples, 0 failures

3. A list of the 10 slowest test items, when measured over the entire test suite run:
