* Base class for local study actions.
*
* This should be subclassed. Subclasses must implement _run() for
* per-recipe behavior, and may implement _finalize for actions to be
* taken once after recipes are run.
*
* For actions that need to be taken once before recipes are run
* _preExecution may be overriden but the overridden method must
* call the parent method to ensure the appropriate checks occur.
*
* Other methods should be overridden with care, to maintain the life
* cycle events and error reporting implemented by this class.
