given a factor graph and its partition {nodeMap}, split the factors between the child cliques ({frontalFactors}) and the current clique ({sepFactors}). Also split the variables between the child cliques ({childFrontals}) and the current clique ({localFrontals}). Those separator variables involved in {frontalFactors} are put into the correspoding ordering in {childSeps}.
