Valgrind on HPC revealed some memory errors which could be result of incorrect calculation of ISA members and thus following pointers to unallocated RAM. I've tried to fix this by coopting the EvalCapsule to traverse the tree to ISA locations. Will test now on Chameleon to see if results are okay, and on HPC to see if memory problems resolved. For FMMtest have less than 1 percent max error with pMax=8
