Subject: use a specific exception when nextTo breaks
X-Git-Url: http://woldlab.caltech.edu/gitweb/?p=mussa.git;a=commitdiff_plain;h=f53ddd693fe894f0f6ab117a01064a9155daf5d6

use a specific exception when nextTo breaks
throw conserved_path_size_mismatch, hopefully we can catch it at some point
and then reset that analysis (hopefully).

I'd like to know why it breaks?
