// <etymology>
// MSSpwParse is the class used to parse a spectral window selection command.
// </etymology>
// <synopsis> MSSpwParse is used by the parser of spectral window
// (Spw) sub-expression statements. The parser is written in Bison
// and Flex in files MSSpwGram.y and .l. The statements in there use
// the routines in this file to act upon a reduced rule. Since
// multiple tables can be given (with a shorthand), the table names
// are stored in a list. The variable names can be qualified by the
// table name and will be looked up in the appropriate table.
//
// The class MSSpwParse only contains information about a table
// used in the table command. Global variables (like a list and a vector)
// are used in MSSpwParse.cc to hold further information.
//
// Global functions are used to operate on the information.
// The main function is the global function msSpwCommand.
// It executes the given STaQL command and returns the resulting ms.
// This is, in fact, the only function to be used by a user.
// </synopsis>
// <motivation>
// It is necessary to be able to give a ms 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>
//# <todo asof="$DATE:$">
//# A List of bugs, limitations, extensions or planned refinements.
