// Class : SliderTable
// 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.
