// <synopsis>
// This class provides read-only access to the columns in the MeasurementSet.
// It does the declaration of all the Scalar and ArrayColumns with the
// correct types, so the application programmer doesn't have to
// worry about getting those right. There is an access function
// for every predefined column. Access to non-predefined columns will still
// have to be done with explicit declarations.
// <note role=warning> The Table that is used to construct this class must not
// be destroyed (or go out of scope) before this class does. Otherwise the
// scalar and array columns use by this class will be left dangling.</note>
// </synopsis>
// </synopsis>
//
// <example>
// <srcblock>
// // use as follows
// MeasurementSet ms("myMS");
