+Rescaled variables used in SIS B-grid dynamics

   Rescaled variables used inside of the SIS B-grid dynamics code or passed to
SIS_B_dynamics for expanded dimensional consistency testing.  These changes
include passing new unit_scale_type arguments to several subroutines.  All
answers are bitwise identical, but there are new arguments and the dimensions
of some arguments have been rescaled.
