pass neurodata_type_def refinements into ObjectMapper.build

[ajtritt]

Problem/Use Case

When using an existing neurodata_type (using neurodata_type_inc), you are allowed to further refine the neurodata_type specification without declaring a new neurodata_type (using neurodata_type_def).

Currently, the TypeMap and ObjectMappers do not know about these further refinements when building the Builder representation.

• modify BuildManager.build, TypeMap.build to accept these further refinements.
• modify ObjectMapper.build to accept these further refinements
  • modify ObjectMapper.__add_groups
  • modify ObjectMapper.__add_datasets
  • modify ObjectMapper.__add_containers
  • modify ObjectMapper.__add_attributes
• ensure the logic recurses
