Choose initial position of MCMC #116

Closed henry-ngo closed 5 years ago

henry-ngo commented 5 years ago

Currently walkers are started in positions that are uniformly drawn from the Prior space.

~Perhaps users can pass an argument specifying an initial guess for each parameter and a sigma value and we can draw walker positions from this distribution.~

~For more advanced users, we should have a convenience function that lets users create their own list of start positions and then update sampler.curr_pos with this list.~

Decided to write a tutorial on how to modify this instead, for now.
