/*

 This module allows for dynamic modification of integer and floating-point

 constants at run-time.

 Place the M() around values you want to allow to be changed at run-time.

 When you want to modify a value, simply change the value in the source

 code file and call ReparseModValues() within your program to re-read the

 source files, checking for changes in constants.  Your program will need

 to contain some trigger such as a key combination to trigger the

 ReparseModValues() call.

 Example:

        x = x + M(2.1);

 Caveats:

        This module determines which files to parse through (during

        ReparseModValues()) at run-time, so if a M() macro has not yet been

        executed within a particular source file, its value will not be

        updated.

 Performance:

        There a small setup cost the first time each M() value is accessed

        after program startup and reparsing, but after that there is just the

        tiny overhead of a function call and a few vector dereferences.
