the class Samcra method computeP2pPath.

/* Samcra Algo:
     *
     * To limit the modification outside the Samcra method the same set of parameters as
     * the CSPF method is used (related to pseudo code, the path length is computed inside
     * the method based on the individual constraint parameters).
     *
     * On contrast to a simple CSPF algo, with Samcra a connected vertex might be associated to several
     * metric vectors from which different path lengths are computed. However a connected vertex is only
     * present once in the priority queue, associated to the minimal path weight, which is used as key
     * to address the priority queue.
     *
     * For a given metric the path weight is an integer value computed as the entire part of
     * the quantity:
     *      100 * (vector_path_metric/target_metric)
     * The path weight correspond to the maximum length computed from either the delay or TE metric.
     *
     * To maintain the priority queue behavior unchanged, a "SamcraPath" classes is created to manage
     * the set of possible paths associated to a given vertex (see above).
