Updated the RegKey and RegEntry cxlasses to contain get methods to
retrieve summarized data which could previously only be printed to STDOUT.

Fixed erroneous comments and provided more explanation throughout to
better help one understand each part of the RegKey and RegEntry classes. I
am working to ensure standardized language throughout. Also, the TODO list
will now be culmulative. It makes me feel good about myself to see
progress. lol

All methods within the RegKey and RegEntry classes now have tests in
easyRegUnitTests.py except for the print methods which will be added
shortly. I also require a machine [LOCATED] with Administrator access so
that I can properly write unit tests for the rest of the easyReg module.
