Detailed Description

The base class for any slave process for simultaneous/combined fits.

Implementation of the JFit method described in arXiv:1409.5080 [physics.data-an].

This class acts as the base class from which slave's should inherit. This allows any fitting framework to plug in to the JFit method.
