//
// This is a pure virtual base-class to provide a table-type agnostic

// access sub-tables and main-table columns of MS-like tables.

//
// <motivation>
//
// To allow use of the <linkto
// module="MeasurementSets:description">MSSelection</linkto> module
// for selection on any table that follows the general structure of the
// MS database. Via this class, minor differences in the database
// layout can be hidden from the MSSelection module. This also keeps
// MeasurementSet module from depending on other MS-like database
// implemention which may use the MSSelection module. Such usage will
// need to implement a specialization of <linkto
// module="MeasurementSets:description">MSSelectableTable</linkto> and
// use it to instantiate the <linkto
// module="MeasurementSets:description">MSSelection</linkto> object.
