## Detailed Description

Stores the total set of VertexSliders that the vertices in a particular GeomVertexData object might depend on.

This is similar to a TransformTable, but it stores VertexSliders instead of VertexTransforms, and it stores them by name instead of by index number. Also, it is only used when animating vertices on the CPU, since GPU's don't support morphs at this point in time.
