+ *
+ *  A source group is a connected set of source measurements with a
+ *  common connection.  Each source in the group represents the
+ *  detection of some astronomical object on a single each.  The group
+ *  represents the related collection of measurements.  The fits are
+ *  coupled in some way.  For example, they may all have the same
+ *  position, but independent fluxes.  Or, they may have a common set
+ *  of positions and shape parameters.  Or the position in each image
+ *  may be related by a function.
+ *
+ *  XXX is thre any info that is neaded for each source group beyond that carried by the sources (besides ID)?
