* Properly name the classes:
* conf -> subisotopologue
* iso -> molecule
* partialExpProbs -> partialProbs
* L... -> log_...
* Types:
* why get_isotopeNo is an int and not a signed int?
* the same with the subisotopologue configurations.
* general WTF:
* get_conf_signature ???
* IsoOrderedGenerator::candidate ???
* IsoOrderedGenerator::terminate_search ???
* IsoLayeredGenerator::advanceToNextConfiguration
* why does it print out things to the console???
* why is advanceToNextConfiguration_internal public, if it's called internal?
* it ain't used anywhere else beyond that class anyway.
