took advice from DNK and http://www.phidot.org/forum/viewtopic.php?f=21&t=515&p=1175&hilit=psi+multistate#p1175 to change transition probability code in a way that fixes a--> B == B-->B.
changed psi model structure to take in new movement code. Output results such that the movement probabilities are structured properly. rEady to run a test with subset of data.
