Functional (but untested) mex file for sampling X and D
Bugfixes for X,D mex. Pretty fast now.
Mex file for computing M and r. Doesn't speed it up a huge amount.
Minor code cleanup for mex files
Changed graphical models to show vector-valued y_n
Added example comparison of varbvs to random on data generated by the
full model. Looks like still beats random. Need to add in Gibbs sampler
testing
Added rudimentary gibbs sampling comparison to the varbvs / "optimal"
test on the full model. Also added a standalone function for sampling a
single Gibbs sweep.
Use gibbs_sweep code in gibbs_test example
