.. rubric:: New Product Occurrence Structure

With Revit, most elements now have a full product occurrences hierarchy more aligned with Revit structure:

* Level product occurrence
* Category product occurrence
* Family product occurrence
* Type product occurrence
* B-rep

This permits us to remove duplication of Type and B-rep instances.
It also made exposition of IDs easier.
Each Type product occurrence nows holds a PersistentID corresponding to the Revit ElementID of the instance.
And for more cross revision identification of instances, each type product occurrence is also exposes its unique ID (Revit EpisodeID + ElementID).

.. rubric:: Mass objects

Support for Revit Mass objects now support reading their geometry as well.

.. rubric:: Unique IDs

We provide a better manager for Unique IDs which are now based on the persistent ID and a session ID.
