Handling global variables across source files

[AumitLeon]

Need a clean and concise way of handling global variables across our source files. Ideally, global variables will be declared and initialized within a single file (i.e a settings.py, or something similar). An example usage might look like the following:

settings.py:

# Initialize and store global variables

def init():
    global __version__
    __version__ = "0.1.0"

other.py:

import settings

# initialize variables
settings.init()

# Should print: The version is 0.1.0
print "The version is: " + settings.__version__

The above is a simple example of how global variables can be sourced and consumed.
