* Class to encapsulate preregistration duties |

|

15 |
|
* This class permits the CNF stream implementation to reach into the theory |
16 |
|
* engine to preregister only those terms with an associated SAT literal (at |
17 |
|
* the point when they get the SAT literal), without having to refer to the |
18 |
|
* TheoryEngine class directly. |
