Add compactly supported transition kernel
Implement new transition kernel for bounded domains
Add joint pdf docs for invlogitgaussian
Add docs for invlogitgaussianvectorrv
Add docs for InvLogitVectorRealizer
Add docs for the new TK
Fix some bugs in the invlogit distribution

1. Deal with the pdf at the boundary better
2. Fix a bug where the wrong transform was being taken for left-open domains
Update regression tests with new reference solns

We need to do this because the transition kernal as changed for DRAM and so
different samples are drawn.
Update ignores.  It's bad these keep piling up
Fix a comment
Update changelog
Remove trailing whitespace
Transform initial proposal covariance matrix

This transforms the initial proposal covariance matrix onto a domain where
there is no boundary and so the proposal covariance is a legitimate Gaussian
distribution.

There's also some trailing whitespace I removed and turned on logging for one
of the regression tests.
Transform samples before adapting proposal cov mat
Make error a warning instead
Adding regression test
Make the rv() getters const methods!
Fix doxygen latex errors
Adding getters for seq gen and transition kernel
Holy trailing whitespace batman
