Super4PCS V1

This new release of Super4PCS introduces major changes in the code structure.

Most efforts have been put on dependencies removal: Super4PCS can be build with a single dependency: the Eigen library.

As a result, Super4PCS CMake project's can now be loaded using Microsoft Visual Studio (with CMake plugin, MVS-2017 recommended). Documentation has been updated accordingly.

We have also improved testing, and now share demo datasets that are compiled directly at compile time.
