There are now multiple versions of ARCamera files and Annotation files

[himanshunaidu]

There are 3 versions of files related to ARCamera:

1. ARCamera (main): iOSPointMapper
2. ARCamera (test): iOSPointMapper
3. ARCamera (Base): PointNMapShared

There are 3 versions of files related to Annotation:

1. Annotation (main): iOSPointMapper
2. Annotation (Base): PointNMapShared

Need to find some possible ways to reduce this redundancy.
