** \brief Class to encapsulate preregistration duties
**
** Class to encapsulate preregistration duties. This class permits the
** CNF stream implementation to reach into the theory engine to
** preregister only those terms with an associated SAT literal (at the
** point when they get the SAT literal), without having to refer to the
** TheoryEngine class directly.
