** \brief LemmaChannels is a light container for a pair of input and output
** lemma channels.
**
** LemmaChannels is a light container for a pair of input and output
** lemma channels. These contain paramaters for the infrequently
** used Portfolio mode. There should be exactly one of these per SmtEngine
** with the same lifetime as the SmtEngine. The user directly passes these as
** pointers and is resonsible for cleaning up the memory.
**
** Basically, the problem this class is solving is that previously these were
** using smt_options.h and the Options class as globals for these same
** datastructures.
