Detailed Description

Container for arrays of parametric patches.

PatchTable contains topology and parametric information about the patches generated by the Refinement process. Patches in the table are sorted into arrays based on their PatchDescriptor Type.

Note : PatchTable can be accessed either using a PatchHandle or a combination of array and patch indices.

XXXX manuelk we should add a PatchIterator that can dereference into a PatchHandle for fast linear traversal of the table
