/**
* Class LAYER_WIDGET
* is abstract and is derived from a wxFormBuilder maintained class called
* LAYER_PANEL_BASE. It is used to manage a list of layers, with the notion of
* a "current" layer, and layer specific visibility control. You must derive from
* it to use it so you can implement the abstract functions which recieve the
* events. Each layer is given its own color, and that color can be changed
* within the UI provided here. This widget knows nothing of the client code, meaning
* it has no knowledge of a BOARD or anything. To use it you must derive from
* this class and implement the abstract functions:
* <p> void OnLayerColorChange( int aLayer, int aColor );
* <p> bool OnLayerSelect( int aLayer );
* <p> void OnLayerVisible( int aLayer, bool isVisible );
* <p> void OnRenderColorChange( int id, int aColor );
* <p> void OnRenderEnable( int id, bool isEnabled );
