Add a command to create a Python wheel through setuptools

[allardhoeve]

There is packaging in place to build a Python package, but it does not currently compile correct wheels. This PR adds a target to build a wheel that compiles the .whl file through standard Python tooling: setuptools.

This creates a binary that has the correct name for current Pythons (_btk.cpython-37m-darwin.so and such).

This can then be released through Pipy (which is currently behind) for various platforms, without the need for users to compile anything.

(Contains #26)

Hello

i am compiling with python 3.7 under windows 7 ( cmake 3.3 and nmake). I am not an expert in c++ compiling
The wrapping works fine in release mode but i suppose i should get a folder "package" inside "bin". I don t have it ! I suspect it s beause i have this warning with cmake during configuration

Make Warning (dev) at Packaging/CMakeLists.txt:1 (ADD_CUSTOM_TARGET):
Policy CMP0037 is not set: Target names should not be reserved and should
match a validity pattern. Run "cmake --help-policy CMP0037" for policy
details. Use the cmake_policy command to set the policy and suppress this
warning.

The target name "package" is reserved or not valid for certain CMake
features, such as generator expressions, and may result in undefined
behavior.
This warning is for project developers. Use -Wno-dev to suppress it.

any help would be appreciated

Hey! I'm also not very experienced, but I had hoped you were :) I think we can safely rename the package target to something else. I'll rename it later this week and see what happens. Allard
