Blatter-Pattyn Boundary Conditions
Boundary conditions + masking, one sided differences, basal BC (no-slip, viscous, and plastic behavior all through Beta^2 implementation)
NEED: sfc and basal BC description from HO model descrip. doc
TO DO: add links from previous pages discussing BP equations and BP numerical solution
