merging in changes from the rma_trunk and commiting
a simple group communicator for distributing the ensemble
mean.  New subroutine my_vars_to_mpi_groups, which takes a 
state ensemble handle and returns a mean handle that is
distributed in groups of group_size.  Everything compiles
but does not work as expected. I will continue on Monday.

+The Earth radius is nominally 6,371 Km.  If you want the
+maximum horizontal distance that an observation can possibly
+influence something in the model state to be X km, then set
+the cutoff to be (X / 6,371) / 2.  Remember the actual impact will
+depend on a combination of this distance and the regression
+coefficient computed from the distribution of forward operator values 
+and the ensemble of values in the model state.
