DS-Stop

DS-Stop is a simple mixin type that allows an authorized account to disable and enable functions on deriving types via a stoppable modifier. It is useful in situations where one needs to halt a system for maintenance, in case of emergency, or simply to wind it down after a temporary lifespan.

DSStop

Your contract should inherit from the DSStop type if you want an admin address to be able to disable/enable any of its functions.
