+ ** 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.
