Determine a PSFEX PSF model for an exposure given a list of PSF
candidates.
Parameters
----------
exposure: `lsst.afw.image.Exposure`
Exposure containing the PSF candidates.
psfCandidateList: iterable of `lsst.meas.algorithms.PsfCandidate`
Sequence of PSF candidates typically obtained by detecting sources
and then running them through a star selector.
metadata: metadata, optional
A home for interesting tidbits of information.
flagKey: `lsst.afw.table.Key`, optional
Schema key used to mark sources actually used in PSF determination.
Returns
-------
psf: `lsst.meas.extensions.psfex.PsfexPsf`
The determined PSF.
