SimpleCycleManager

Short summary

An implementation of the ISinlgeExecutionCycleManager to provide simple cycle managment for steps in state machines. The body NEEDS to be called at the start of every cycle (before using the step property) ONLY ONCE.

.. <info> If used in the same step, the order of method calls should be this: configurations enter executeCommand evaluate waitFor proceed proceedWith acknowledge leave .. </info>
