Comply to the common mobility naming conventions

[chaitan94]

This is to make sure that MobilityDB and MEOS have similar naming schemes.

For more discussion on this, check https://github.com/MobilityDB/MobilityDB/issues/18

Pending:

• [x] MEOS: Rename Geometry to GeomPoint
• [x] PyMEOS: Move base type before temporal duration in the naming convention throughout. i.e, for example, remove TSequenceSetGeom and add TGeomPointSeqSet.
• [x] MEOS: Add typedefs, ex. typedef TSequenceSet<int> TIntSeqSet; so that both are available, and with the latter, C++ API can stay in line with PyMEOS API as well.
