Parameters:

concept1 - required - concept id

concept2 - required - concept id

conceptFilter - optional. map of concept id to relevance (infogain) for all concepts. Only lcses from this map will be considered.

simInfo - optional. if provided, we will fill in the path information and lcs of simInfo

Returns:
