Check usage of parallel states

Check ID: mathworks.jmaab.jc_0721

Guideline: jc_0721: Usage of parallel states

Parallel states must not be used for the purpose of grouping that is the substates of parallel states must not be parallel states.

This check requires a Simulink^® Check™ and Stateflow^® license.

This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.

For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:

Condition	Recommended Action
Parallel states are only for grouping.	Substates of the parallel states must not be parallel (do not use for grouping).

Runs on library models.
Analyzes content of library-linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to graphical.
Allows exclusions of blocks and charts.

This check is supported by edit-time checking.
