/// As you can see, several global items are defined when you use the ConsoleFunction method.
/// The macro constructs the name of these items from the parameters you passed it. Your
/// implementation of the console function is is placed in a function with a name based on
/// the actual name of the console funnction. In addition, a ConsoleConstructor is declared.
///
/// Because it is defined as a global, the constructor for the ConsoleConstructor is called
/// before execution of main() is started. The constructor is called once for each global
/// ConsoleConstructor variable, in the order in which they were defined (this property only holds true
/// within file scope).
///
/// We have ConsoleConstructor create a linked list at constructor time, by storing a static
/// pointer to the head of the list, and keeping a pointer to the next item in each instance
/// of ConsoleConstructor. init() is a helper function in this process, automatically filling
/// in commonly used fields and updating first and next as needed. In this way, a list of
/// items to add to the console is assemble in memory, ready for use, before we start
/// execution of the program proper.
///
/// In Con::init(), ConsoleConstructor::setup() is called to process this prepared list. Each
/// item in the list is iterated over, and the appropriate Con namespace functions (usually
/// Con::addCommand) are invoked to register the ConsoleFunctions and ConsoleMethods in
/// the appropriate namespaces.
