Writing a space warp plug-in involves creating instances of two key classes.
One is derived from class WSMObject. (WSMObject stands for Word Space Modifier Object,
just another name for Space Warp Object). The other class is subclassed off Modifier.
These two classes work together. The space warp object handles the display and management
of its user interface parameters, the display of the space warp node in the scene, and
provides a world space orientation. The space warp modifier handles the actual deformation
of the geometry of nodes bound to the space warp. Each node bound to the space warp
will have a ModContext which we will store data in.
The following class is the WSMObject for the westwood skin modifier.
