// MSPolnParse is the class used to parse a polarization selection command.
// </etymology>
// <synopsis>
//
// MSPolnParse is used by the parser of polarization sub-expression
// statements of the type [SPW:]POLN. Since this is a relatively
// simple expression to tokenize and parse, this parser is written
// without Bison or Flex. The methods of this class take an
// expression, and internally generate a list of the Data Description
// IDs that should be used to select the rows in the MS main table.
// The map of Polarization IDs (row numbers in the POLARIZATION
// sub-table) and the list of indices to be used to pick the user
// selected polarzation data (in the DATA columns of the MS main
// table) is also generated. This map is intended to be used along
// with the map of SPW and selected channels to apply the in-row
// selection (Slice on the data columns).
//
// </synopsis>
// <motivation>
// It is necessary to be able to give a data selection
// command in ASCII. This can be used in a CLI or in the table
// browser to get a subset of a table or to sort a table.
// </motivation>
