Message:

Changes to the creation of "matched" sources for forced photometry in psphotStack to
reduce the number of false sources.
New recipe values PSPHOT.STACK.MIN.DETECT.FOR.FORCED and PSPHOT.STACK.MATCH.FILTERS are added..
The latter is an array (actually metadata) of metadatas an entry for each filter.
Contained in each entry are two values ORDER and MATCH.ALL.
When matching objects the inputs are processed in the defined order. (The intent is that
more sensitive bands are to be processed first.)
If the number of detections for each object is less than PSPHOT.STACK.MIN.DETECT.FOR.FORCED
(set to 2 here) matched sources are not created unless one of the detections was in a
bad for which MATCH.ALL is set. This is currently only true for y band.
This reduces the number of suprious sources.
Note that the entries defined in PSPHOT.STACK.MIN.DETECT.FOR.FORCED are the PS1 bands.
If psphotStack is supplied inputs whose FILTER.ID is not in the defined set, then will be processed
fine, being processed in order supplied following any inputs which do have entries.
