Medium

Please provide a clear description of problem you would like to solve.

In cuspatial/_lib/cpp we create the bindings for libcuspatial functions. These files must 1-1 match the folder structure of how libcuspatial organizes its column APIs. Currently they are out of place and should be cleaned up.
