Summary:

Move writer callbacks used in the HMC code into the active ps_point object.

Description:

Write now info and error writer callbacks are threaded through much of the HMC code in order to catch potential autodiff errors, making my functions awkward to call. The code would be drastically simplified by making the callbacks members of the base ps_point class that is already passed into each of these functions.

Current Version:

v2.13.1
