// The following is a typical way of using this class and its methods ...
//
// <srcblock>
// MSTransform *mst = new MSTransform();
// </srcblock>
//
// Create a Record with the desired parameters. The parameters are: data selection parameters and any parameters
// for the transformations.
//
// <srcblock>
// Record params = Recod();
// params.define("spw", "0,1,2");
// params.define("combinespws",true);
// mst->configure(params);
// </srcblock>
//
// Open the MS, select the data and setup the output MS.
//
// <srcblock>
// mst->open();
// </srcblock>
//
// Run the tool and afterwards, destroy any instance of it by calling the destructor.
//
// <srcblock>
// mst->run();
//
// mst->done();

// <motivation>
// To avoid multiple read/writes of the data....
