Detailed Description

A helper class for MSFitsInput.

Intended use:

Internal

Etymology

This class can hold a primary group of several datatypes

Synopsis

This is a helper class to avoid cumbersome switch statements on the template type of the primary group It forwards all the PrimaryGroup member functions we need in the filler.
