Base class for PSF determiners.
Register all PSF determiners with the psfDeterminerRegistry using: psfDeterminerRegistry.register(name, class)

Construct a PSF Determiner @param[in] config an instance of pexConfig.Config that configures this algorithm @param[in,out] schema an instance of afw.table.Schema used for sources; passing a schema allows the determiner to reserve a flag field to mark stars used in PSF measurement, but some PSF determiners ignore this argument

) |
Determine a PSF model @param[in] exposure exposure containing the psf candidates (lsst.afw.image.Exposure) @param[in] psfCandidateList: a sequence of PSF candidates (each an lsst.meas.algorithms.PsfCandidate); typically obtained by detecting sources and then running them through a star selector @param[in,out] metadata a place to save interesting items @return - psf: the fit PSF; a subclass of lsst.afw.detection.Psf - cellSet: the spatial cell set used to determine the PSF (lsst.afw.math.SpatialCellSet)
