51 // <synopsis>
52 // This class converts a version 1 MeasurementSet to version 2.
53 // The keyword MS_VERSION tells the version. If not present it is 1.
54 // If it is found that the MS is already a version 2 one, nothing is done.
55 // <p>
56 // It is possible to do the conversion in place. If not, first a copy
57 // is made which is thereafter changed in place.
58 // <br>
59 // The conversion process does the following steps:
60 // <ul>
61 // <li> Create the newly required columns and keywords
62 // and fill them with new or existing data.
63 // <li> Convert the old way of defining measure info to the new
64 // TableMeasures way.
65 // <li> Rename obsolete columns by prefixing their names with _OBSOLETE_.
66 // </ul>
67 //
68 // The constructor only keeps the names of the input and output MS.
69 // The actual conversion is done by the <src>convert</src> function.
