/**
 * Describes an editor whose behavior is not altered by the value being
 * displayed.
 * 
 * Editors, which may be classes or interfaces, may expose their sub-editors in
 * one or more of the following ways:
 * 

 * An instance field with at least package visibility whose name exactly is
 * the property that will be edited or propertyNameEditor.
 * 
 * A no-arg method with at least package visibility whose name exactly is
 * the property that will be edited or propertyNameEditor.
 * 
 * The {@link Path} annotation may be used on the field or accessor method
 * to specify a dotted path or to bypass the implicit naming convention.
 * Sub-Editors may be null. In this case, the Editor framework will ignore
 * these sub-editors.
 * 
 * Any exposed field or method whose type is Editor may also use the
 * {@link IsEditor} interface to provide an Editor instance. This allows view
 * objects to be written that can be attached to an Editor hierarchy without the
 * view directly implementing an Editor interface.
 * 
 * @param  the type of object the editor displays.
