Fix various issues with generated C++ (#798)

* Fix various issues with generated C++

Closes #797

* frc namespace, add override keyword

* Capital 'P' in 'Process'

* Fix integer division in filterContours

Closes #810

* Remove include for contrib module

* Clean up generated doc comments

* Capitalize C++ getter methods

All public C++ functions should be PascalCase now
