// MSCorrParse is the class used to parse a corr command.
// </etymology>
// <synopsis>
// MSCorrParse is used by the parser of UV dist sub-expression statements.
// The parser is written in Bison and Flex in files MSCorrGram.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 MSCorrParse only contains information about a table
// used in the table command. Global variables (like a list and a vector)
// are used in MSCorrParse.cc to hold further information.
//
// Global functions are used to operate on the information.
// The main function is the global function msCorrCommand.
// 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.
