Create Weihenstephan state machine specialization

[shaun-edwards]

The Weihenstephan standard shown as a OMAC / PackML V3.0 model below (taken from PackML V3.0 standard), is a typical industrial state machine. It also has the benefit of having fewer user interactions to "start" a machine. From a "Stopped" state, a machine can be simply be started. The PackML standard requires a "reset" and then "start". From an aborted state, the PackML standard requires three operations.

NOTE: The figure below does not show an "un-holding" state. This transitory state is inconsequential to user operations, and potentially useful for customization. I recommend keeping the state.
