 Cautions
 B estimation is not entirely stable--at least with more than 2 spp and unconstrained Q and R. 
 
-Version 2.68 Sept 24, 2009
+Version 2.69 Oct 4, 2009
+added states.se to output list
 fixed stderr computation in the emHessian() function; typo
 pulled the stderr and CI calculations into a helper function computeCIs()
 blocked B estimation when B is diagonal and Q is not diagonal; something is wrong with the computation; perhaps there are multiple solutions (not fully constrained problem)
