BUD switch

The BUD Switch is a block planned to be added in the Redstone Update for use with redstone circuitry. BUD stands for Block Update Detector and configurations of such a device have existed in Minecraft due to a glitch labelled as a "feature", allowing circuits to detect block updates, using a piston powered in a way it does not recognise until it has been updated by using blocks such as growing grass or decaying leaves or having to place a block. This block will simplify the process into one block.
