      public String registerReusableJoin(String sourceIdPath, String relationship, String targetId)
      Registers a "reusable" join, returning a preexisting ID if the join is already registered. Reusable joins are the implicit inner joins that are added as a result of processing of path expressions in SELECT or WHERE clauses. Note that if an implicit INNER join overlaps with an explicit INNER join, both joins are added to the query.
