// 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. :)

// !Panel: Key-based translation of a panel or dialog text; usually either a header or

//
// !Notice: Key-based translation of a popup dialog box; either a notice, confirmation,
// or error. These typically have very high translation priority (roughly equal
// or slightly less than pxE_Panel).
//
// !Tooltip: Key-based translation of a tooltip for a button on a tool bar. Since buttons are
// rarely self-explanatory, these translations are considered medium to high priority.
//
// !Wizard Key-based translation of a heading, checkbox item, description, or other text
// associated with the First-time wizard. Translation of these items is considered
// lower-priority to most other messages; but equal or higher priority to ContextTips.
//
// !ContextTip: Key-based translation of a tooltip for a control on a dialog/panel. Translation
// of these items is typically considered "lowest priority" as they usually provide
// only tertiary (extra) info to the user.
