Examples of using XRC files and extending XRCed.

custom1.py
	Example of adding a custom control (LEDNumberCtrl from gizmos
	package). This file contains three parts: XML handler class,
	XRCed interface class (used only by XRCed) and a section which
	is executed if it is run as a script to actually use the
	control.

custom1.xrc
	XRC file for custom1.py. If you load it in XRCed "custom" menu
	will appear in tree pulldown menu, populated with just one
	item "LEDNumberCtrl".

custom2.cpp
	Example of adding the same custom control, this time using C++
	XML handler. This file is used twice: firstly to build a
	shared library "led.so" which is used by XRCed to initialize
	the resource handler and secondly to compile an executable
	"custom2" which creates the same window as custom1.py (but in
	pure C++).

custom2.py
	Standalone XRCed interface class (the second part of
	custom1.py).

custom2.xrc
	Same as custom1.xrc but uses a different comment directive for
	loading "led.so" shared library instead of Python module.

Makefile
	Makefile for UNIX. wx-config should be in PATH.

plugins/
	Same as before but done in plugin-like manner. XRCEDPATH 
	environment variable should be specified (can be simply
	'plugins' if xrced is run from examples/ directory).
