Perform a single fit cycle of FGCM. This task runs a single "fit cycle" of fgcm. Prior to running this task one must run both fgcmMakeLut (to construct the atmosphere and instrumental look-up-table) and fgcmBuildStars (to extract visits and star observations for the global fit). The fgcmFitCycle is meant to be run multiple times, and is tracked by the 'cycleNumber'. After each run of the fit cycle, diagnostic plots should be inspected to set parameters for outlier rejection on the following cycle. Please see the fgcmcal Cookbook for details.
