Refactoring of geometry classes:

Refactoring of geometry classes:
- AliMUONGeometryModules are accessed via a new AliMUONGeometry class
- Transformations data are separated in  AliMUONGeometryTransformer,
  AliMUONGeometryModuleTransformer classses
- AliMUONGeometryDetElement objects contain always transformation in
  a new ALIC refernce frame
- Read/Write functions moved from AliMUONVGeometryBuilder
  in AliMUONGeometry (svmaps) and AliMUONGeometryTransformer
(transformations)
