Detailed Description

A mock of ReferenceObjectLoader using catalogs in memory.

Parameters
----------
catalogs : `list` [`lsst.afw.table.SimpleCatalog`]
    In-memory catalogs to use to mock dataIds.
config : `lsst.meas.astrom.LoadReferenceObjectsConfig`, optional
    Configuration object if necessary to override defaults.
htmLevel : `int`, optional
    HTM level to use for the loader.
