started reformatting Model type
Added tensor field in MCMCLikelihoodModel (i.e. derivatives of Hessian, needed for geometric MCMC samplers)
Minor tensor-related correction in autodiff MCMCLikelihoodModel version (I had missed a "nothing" argument)
Started porting RMHMC
Minor changes (use of isfinite in two places, renaming of beta to pars and of ll to logtarget, change of older MCMCModelWithGradient to MCMCModel in HMC and MALA)
Starting with RWM tuners (starting with a constant tuner, aka non-tuning option)
Set RWM to work optionally with or without tuning (tuner still needs to be implemented)
Added diagnostics field to MCMCSample and AcceptanceRater type (to be shared among all samplers). Work in progress..
Made devel operational after model changes (fixed bugs and made slight change in RWM algo)
Merge pull request #10 from JuliaStats/devel

Model-related types operational after recent changes
