- split Far::PatchDescriptor into its own class (mirrors Far::PatchParam) - hide PatchArray as a private internal structure - add public accessors patterned after Far::TopologyRefiner (returning Vtr::Arrays) - propagate new API to all dependent code note: some direct table accessors have not been removed *yet* - see code for details
