Addressing divergent transitions #1

Efforts to tweak model and tuning parameters to squash divergent transitions have not been successful. Let the following measure be tried to help solve this issue:

Simulate data from the model (logodds_glfp) of a size that permits faster fitting 20 groups, 100 units per group, censoring approx. 50%

"True" hierarchical distributions can be determined by setting hyperparameters to the prior mean (or at some other reasonable value, e.g. tau_ls1 between .1 and .5.)
