public class Sequencer
extends org.lsst.ccs.framework.Module

A generic sequencer module. This sequencer module can call methods, set values, sleep for some delay, wait for some state change or update value broadcast, loop... It can accept commands and act as a facade of a whole ModularSubsystem. TODO this should use Groovy DSL
