you can also enter extra geometries, i.e. middle and end geometries, to define the path. The labels of these geometries are "midgeom", "endgeom", e.g.

This run never really converges well because the two H's that are doing all the real work pop off to form H2 and do a little dance and then come back to the CH2 group they left behind. Optimizing the details of the little dance is about as likely has finding blinker fluid at the auto parts store

Note that this sends H1 right through the Carbon - atom avoidance code must work

permanent_dir ./permh
scratch_dir ./permh
