Added Support object as an indicator of support for a function and pairs
of functions. Put effort into keeping lists sorted as required by
project guidelines.
Created some JUnit tests to ensure the Support object is always behaving
as anticipated. Test-driven development already helped me find a few
kinks before they became confusing problems :)
Got more of a start on the call graph parsing. Now nodes can be added as
a denominator in confidence. Callsites are also tracked.
