bpy.types
All widgets and operators dynamically appear in the bpy.types listing object. Care must be taken to give your operator a unique class name, and a unique 'bl_idname'. By not giving a unique name you can override blender's default behavior or interface. For example lets override the INFO menu with extra buttons.
