a82fa04d8a Python: Add worked example of taint step modeling of external libs 
This can't be seen on the example, but I went through quite a lot of iterations
before arriving at this fairly simple solution.

00ea0cebc3 Python: More Flask modeling kinda works 
It "kinda" works now, but it really is not a pretty solution. Adding all these
"tracked" objects is SUPER annoying... it _would_ be possible to skip them, but
that seems like it will give the wrong edges for dataflow/taintflow queries :|

A good chunk of it should be able to be removed with access-paths like C# does
for library modeling. Some of it could be solved by better type-tracking API
like API Graphs... but it seems like we generally are just lacking the
nice-to-have features like `.getAMemberCall` and the like. See
