Detailed Description

A helper class for CoaddInputRecorderTask, managing the CoaddInputs object for that a single
CoaddTempExp.  This will contain single 'visit' record for the CoaddTempExp and a number of 'ccd'
records.

Should generally be created by calling CoaddInputRecorderTask.makeCoaddTempExp().
