Detailed Description

Select sources based on whether they are isolated

This object can be used as a `lsst.pex.config.Config` for configuring
the column names to check for "parent" and "nChild" keys.

Note that this should only be run on a catalog that has had the
deblender already run (or else deblend_nChild does not exist).
