      Fix improper declaration of shared-pointer base class. · 98222212
      David Thompson authored 
      When inheriting classes that provide `shared_from_this()`,
you must specify the oldest ancestor (which directly inherits
the `enable_shared_from_this<T>` class), not any intermediate
ancestors. Many classes were inheriting smtk::resource::Resource
but it is now smtk::resource::PersistentObject that holds the
pool of shared pointers. This could lead to leaks when subclasses
have their `shared_from_this()` method invoked.

      Add a geometry subsystem to SMTK.. · 109b548a
      David Thompson authored 
      We are working toward removing smtk::model::Tessellation in order
to resolve performance problems inherent in its design.
In its place is smtk::geometry::Geometry and subclasses that allow
developers an efficient (usually zero-copy) technique for providing
access to their geometry directly in the format that rendering
and analysis backends will use.

This first step simply adds smtk::geometry::Geometry but does
not force its use or remove smtk::model::Tessellation.
