- * Routines for manipulating the order of a multiple sequence alignment

- * TODO: refactor to allow a subset of selected sequences to be sorted within the context of a whole alignment.
- * Sort method template is: SequenceI[] tobesorted, [ input data mapping to each tobesorted element to use ], Alignment context of tobesorted that are to be re-ordered, boolean sortinplace, [special data - ie seuqence to be sorted w.r.t.])
- * sortinplace implies that the sorted vector resulting from applying the operation to tobesorted should be mapped back to the original positions in alignment.
