Update changelog

This new release of Super4PCS introduces major changes in the code st…

…ructure.

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.

For more details, checkout the complete CHANGELOG at the code source root directory.
