This adds a new type of MCMC Proposal, MCMCMultiProposal which allows to draw MCMC samples from different types of proposals during sampling. Either according to a Categorical Distribution or to a fixed schedule.

Also a new type of Adaptive Transformation is added which allows to use chains of several Adaptive Transformations for MCMC sampling.
