CVS commit by staikos: 

equation objects now automatically detect changes in vector names and rewrite
the equation accordingly.  Some formatting is lost, but in general it seems to
work.  Causes a small performance hit on saving equations since they are
reparsed and then the tree is walked.

Required changing collectVectors to use a map instead of a list.

Negatives are temporarily a bit broken
