@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

@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)
