Feature Selector

Hi,
not sure if this is in the scope of cadquery, but it would be a nice to have a selector that finds specific features like e.g. fillets or drilled holes and then also the ability to defeature/remove these.

http://analysissitus.org/features.html already provides these functionalities on the base of OCC. It provides also a library version in C++ but I can't say if this can be used directly with python.
