** \brief An object to request logic widening in the running SmtEngine
**
** An object to request logic widening in the running SmtEngine. This
** class exists as a proxy between theory code and the SmtEngine, allowing
** a theory to enable another theory in the SmtEngine after initialization
** (thus the usual, public setLogic() cannot be used). This is mainly to
** support features like uninterpreted divide-by-zero (to support the
** partial function DIVISION), where during theory expansion, the theory
** of uninterpreted functions needs to be added to the logic to support
** partial functions.
