Lou-Zhang-Yoon model with general differentiable yield function.

This module includes the implementation of the Lou-Zhang-Yoon model with general differentiable yield function and isotropic hardening.

The apex singularity is handled by means of a purely volumetric return-mapping along the hydrostatic axis.

It also includes several tools to check the yield surface convexity.
