REFAC: Check for mapping existence possible, OneToOneMap uses ints now
- Adds the ability to check for existence of mapping between points in the OneToOneMap.
- Remove virtual getMapId call in GeometryMap as it only applied to OneToOneMap.
- CollidingObject maps initialized to nullptr.
- Ints used in OneToOneMap to avoid warnings.
- Few other cleanups
