found the bug, reset the 000 cube instead of the 111 for saddlepotentials
fixed a BUG in the original saddle calculation...
optimized matrices yield same energies as old scheme, but knowncase test now fails due to bugfix in original code.
Cleaned out the old code and verified the new.
added more safeguards and some cleaning. Ready for merge.
disassembly checks that kmcd_assert was really optimized to nothing. Ready for merge.
