Using Time Step Control Strategy (TSCS) allows for applications to define their very own time step control strategy and add it to a vector of strategies and the Time Step Control will iterate and call each strategy. Essentially, this could be an and case if each strategies does a min with the step size dt = metaData->getDt() and a new computed step size dt_new before updating the step size with metaData->setDt( DT ).

If the application wanted an or case, they can just appropriately update the metaData->setDt(dt). The TSC, after calling all the TSCS, gets the updated dt by calling metaData->getDt().

Note the ordering in the Time Step Control Strategy List (is important). A final TSCS that is called last can get just negate all previous TSCS updates.

The documentation needs to be updated to make this clear.
