+- Added an additional method `#contractLabeledEdge`, While `#contractEdge` contract all edges (irrespective of their label) between two vertices, `#contractEdge` contracts just one particular edge with a specific label. Note that since cycle are forbidden, a certain labeled edge between two vertices can only be contracted if it is the only edge between those two vertices. `#contractLabeled` refuses two contract in such a case, while `#contractVertices` contract all edges. You can check with `#canContractEdge` and `#canContractLabeledEdge`.
