Added new functions to perform alignment with a "pinned node", where the end of the read must be aligned to the end of the node. This is intended to be used in the MEM threading routine in vg. I also added the ability to return an arbitrary number of alternate pinned alignments in addition to the optimum. These are returned in descending score order from the optimum.
