//  ImplementEnumOperators  (macro)
// --------------------------------------------------------------------------------------
// This macro implements ++/-- operators for any conforming enumeration.  In order for an
// enum to conform, it must have _FIRST and _COUNT members defined, and must have a full
// compliment of sequential members (no custom assignments) --- looking like so:
//
// enum Dummy {
//    Dummy_FIRST,
//    Dummy_Item = Dummy_FIRST,
//    Dummy_Crap,
//    Dummy_COUNT
// };
//
// The macro also defines utility functions for bounds checking enumerations:
//   EnumIsValid(value);   // returns TRUE if the enum value is between FIRST and COUNT.
//   EnumAssert(value);
//
// It also defines a *prototype* for converting the enumeration to a string.  Note that this
// method is not implemented!  You must implement it yourself if you want to use it:
//   EnumToString(value);
//

//  DeclareNoncopyableObject
// --------------------------------------------------------------------------------------
// This macro provides an easy and clean method for ensuring objects are not copyable.
// Simply add the macro to the head or tail of your class declaration, and attempts to
// copy the class will give you a moderately obtuse compiler error that will have you
// scratching your head for 20 minutes.
//
// (... but that's probably better than having a weird invalid object copy having you
//  scratch your head for a day).
//
// Programmer's notes:
//  * We intentionally do NOT provide implementations for these methods, which should
//    never be referenced anyway.

//  * I've opted for macro form over multi-inherited class form (Boost style), because
//    the errors generated by the macro are considerably less voodoo.  The Boost-style
//    The macro reports the exact class that causes the copy failure, while Boost's class
//    approach just reports an error in whatever "NoncopyableObject" is inherited.
//
//  * This macro is the same as wxWidgets' DECLARE_NO_COPY_CLASS macro.  This one is free
//    of wx dependencies though, and has a nicer typeset. :)
