looks more readable match edge

Edge.prototype.matchEdge = function (pEdge){
    //if the indexes match either way round
    return ((this.point0 == pEdge.point0
        && this.point1 == pEdge.point1)
        || (this.point0 == pEdge.point1
            && this.point1 == pEdge1.point0
            && this.vector == false))
    && this.weight == pEdge.weight;
};
