Misfit Le Bail Fitting

Refine lattice parameters for two phases simultaneously, with the option to constrain parameters between them. This is useful for analyzing misfit compounds or composites.

The profile used is GSAS Profile 4. The background is determined using a rolling ball algorithm and fixed during the main refinement.
