These procedures are helpful if you have a structure like this in your source tree and it can be anything like 
Google protobuf, grammar syntax, shared source code of some sort that gets transformed to Python and C++, or 
really anything that has a common base from which it is derived but when included (subtree'd/submoduled in git) 
we only need the language specific part, not the rest.

What we do is create completely new branches in which we place a copy from the proper subdirectory from the 
master branch. Yes that technically means we are duplicating files/commits in two different locations, but it 
is a better option that having your Python specific source tree carrying around C++ files it does not need.
