40 * Routines for manipulating the order of a multiple sequence alignment TODO:
41 * this class retains some global states concerning sort-order which should be
42 * made attributes for the caller's alignment visualization. TODO: refactor to
43 * allow a subset of selected sequences to be sorted within the context of a
44 * whole alignment. Sort method template is: SequenceI[] tobesorted, [ input
45 * data mapping to each tobesorted element to use ], Alignment context of
46 * tobesorted that are to be re-ordered, boolean sortinplace, [special data - ie
47 * seuqence to be sorted w.r.t.]) sortinplace implies that the sorted vector
48 * resulting from applying the operation to tobesorted should be mapped back to
49 * the original positions in alignment. Otherwise, normal behaviour is to re
50 * order alignment so that tobesorted is sorted and grouped together starting
51 * from the first tobesorted position in the alignment. e.g. (a,tb2,b,tb1,c,tb3
52 * becomes a,tb1,tb2,tb3,b,c)
54 public class AlignmentSorter
57 * todo: refactor searches to follow a basic pattern: (search property, last
