Dropped return value from draws in Random objects, time_series stuff not complete...
times_series.cpp still needs the state/parameter functions, and their references in the posterior class probably can't be const, think about splitting bind_X_distribution functions to avoid the repetitive code... maybe change structure now to deal with multivariate distributions...
Simplifying arguments, code cleanup.
All the content form locations.hpp/.cpp moved to time_series.hpp/.cpp...
