Title: Elastic membrane updates

A bit of internal refactoring to ElasticMembrane for dealing with cases where the material is compressible. Added capability for plotting stresses and strains. Still need better stress/strain (i.e. gradient) postprocessing and a knob for playing with compressibility for some of the membranes, but this is good as is.
