Return a list of case roles for the given verb and the given grammar role. The list consists of the case roles which, for this verb, are most likely to fill the given grammar role. The list will be in order of likelihood, from most likely to less likely. For example ("give", SUBJECT) will return [CaseRole.AGENT]; ("give", DIRECT_OBJECT) will return [CaseRole.PATIENT]; ("give", INDIRECT_OBJECT) will return [CaseRole.DESTINATION].

Return a list of prepositions for the given verb and the given case role. The list consists of the prepositions which, for this verb, are most likely to precede the entity filling the given case role. An empty string means "no preposition". The list will be in order of likelihood, from most likely to less likely. For example ("give", Patient) will return "" because for this verb the Patient role does not take a preposition. But ("give", DESTINATION) will return "to".
