Changing the way jitter/ecorr is handled explicitly
Updated Gibbs mark1. Does not work properly when jitter is included
Debugging the new jitter stuff
Fixed the non-expanded jitter in Gibbs mark1
FIXED: mark1 Gibbs sampler now properly works with jitter/ecorr, including expandJitter option
Now Gibbs mark2 needs serious debugging, after committing all the Cython ecorr updates
FIXED: mark2 Gibbs now works. (had a<->b swapped for red noise quadratic samples)
