Adding MM and STGC clusterization packages for the NSW, with interfaces and example tools

This merge request provides a structure to be followed in the future to implement the cluster builders tools, that will have various developers.

We also have a first version of the "simple" cluster builder, right now implemented in the converters, this will be added as soon as this merge request is merged. But this will also imply modifying the clients, so a few more packages involved, it is neater to stage the two MR's.
