Some utility methods for creating SMTK entity records in common arrangemnts.

Track regions not connected by edges but by the sweepline.

Disconnected regions and loops are correctly detected.
Disjoint regions are not merged together; that requires
additional work.

The one needed for the polygon branch is the preview entity,
which is used to hold tessellation information for visual feedback
during a geometric operation.

+ Preview entities may be related to model and/or mesh entities;
+ they may have text notes attached to them to be shown on mouse-hover
  or in a list that is tied to rendering (so that brushing the list
  highlights the preview geometry and vice-versa);
+ they may be associated with attributes, but there is not a use case for this yet;
+ they may have properties associated with them indicating that one
  of several preview entities should be selected to disambiguate an
  operation.

Sessions should not have to make every operator a friend.
This adds methods to the base polygon Operator class to
provide access to the Session's storage.

Python already has a "CreateFace" function (which works for
CGM) but this commit adds "CreateFaces" for expediency in
testing the polygon session. The operators should be reconciled.

Methods like `smtk::model::Model::cellsAs<T>()` and
`smtk::model::Model::groupsAs<T>()` would append cursors
that were invalid rather than omitting values not matching
the container type. For example, calling `model->cellsAs<Edges>()`
should only return cells owned by the model that are edges
(as opposed to vertices, faces, or volumes).
Without this patch, invalid `Edge` cursors were being inserted
for each vertex, face, or volume in the model's set of cells.

When we write out the mesh collections into files on disk while exporting smtk model, which will reference
these mesh files (and model files), we want the mesh and model files to be relative to the smtk file, so that all the files can be bundled together and shared with other people.

While doing edge split/merge in discrete session, if there are edge meshes assoiciated with the modified edges, corresponding ops are also done for the edge meshes now. Including promote and demote vertex, and related mess classifications against the model.

Now when you are iterating the cells with for_each you get the Handle id
for the current cell.
