Using `auto-07p` to continue along instabilities? #57

This is a very general question, but I was wondering if the solver developers had considered auto-07p for bifurcation analysis (for example in the 1D case, link), and if it can be used at all in the 3D case. As I understand, currently solutions cannot be continued in FEBio when they become multivalued. This would be highly useful when it is not known a priori how to break symmetries in the system to favor one solution or another at unknown elastic instabilities.
