org.locationtech.udig.project.IMap
The part of the model that represents a map.
A Map consists of:
- ContextModel - holds on to list of layers
- ViewportModel - the bounds and projection of the current display
  
  Responsibilities:
  - Provide access to the active controllers and models, but not viewers.
  - Create a new map based on the current map is also included
