 Execute a python program and for each call being made, record the call and callee. This allows us to compare call graph resolution from static analysis with actual data -- that is, can we statically determine the target of each actual call correctly.
 
-Using the call graph tracer does incur heave toll on the performance. Expect 10x longer to execute program.

 Number of calls recorded vary a little from run to run. I have not been able to pinpoint why.

-It should be fairly straight forward to expand the set of projects. Most projects use `tox` for running their tests against multiple python versions. I didn't look into any kind of integration, but have manually picked out the instructions required to get going.
