Removed Similarity from Shot 

Problem: Shot was using similarity merely to store
rotation and translation. 
There was an incompatibility in that Similarity::ToMatrix
gives scale*rotation*translation while in Shot
the translation stores the viewpoint and the rotation the orientation of the Shot.

In this version, a small class ReferenceFrame was done to play the role of similarity and MultMatrix and MultSimilarity functions were added to transform the frame by multiplying it for a Matrix44 (or applying a similarity).

NOTE: the file export_ply.ply and import_ply.h must also be updated.
