// It is necessary to be able to give a cal library filename for 
// instructions for on-the-fly calibration.
// This can be given in a CLI or set in a GUI file browser.

// <use visibility=local>

// <etymology>
// CalLibraryParse is the class used to parse a cal library.
// </etymology>

// <synopsis>
// CalLibraryParse is used by the parser of cal library files.
// The parser is written in Bison and Flex in files CalLibraryGram.yy and .ll.
// The statements in there use the routines in this file to complete
// a Record with default and specified calibration parameters.
//
// The class MSFieldParse only contains information about a table
// used in the table command. Global variables (like a list and a vector)
// are used in MSFieldParse.cc to hold further information.
//
// Global functions are used to operate on the information.
// The main function is the global function callibSetParams.
// It parses the given calibration library file and completes
// the given Record.  This is, in fact, the only function to 
// be used by a user.
// </synopsis>
