// This class converts a version 1 MeasurementSet to version 2.
// The keyword MS_VERSION tells the version. If not present it is 1.
// If it is found that the MS is already a version 2 one, nothing is done.
// <p>
// It is possible to do the conversion in place. If not, first a copy
// is made which is thereafter changed in place.
// <br>
// The conversion process does the following steps:
// <ul>
// <li> Create the newly required columns and keywords
// and fill them with new or existing data.
// <li> Convert the old way of defining measure info to the new
// TableMeasures way.
// <li> Rename obsolete columns by prefixing their names with _OBSOLETE_.
// </ul>
//
// The constructor only keeps the names of the input and output MS.
// The actual conversion is done by the <src>convert</src> function.
// </synopsis>
