Check for state in state machines

Check ID: mathworks.jmaab.db_0137

Guideline: db_0137: States in state machines

Identifies states with OR(exclusive) type decomposition with only one sub-state.

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
One or more states with OR(exclusive) type decomposition have only one sub-state in the model.	Remove the sub-state or add another state.

Runs on library models.
Allows exclusions of blocks and charts.
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.

This check is supported by edit-time checking.
