52 * construct includes regex qualified tokens which are replaced with seuqence
53 * IDs ($SEQUENCE_IDS$) and/or seuqence regions ($SEQUENCES$) that are
54 * extracted from the group. See <code>UrlLink</code> for more information
55 * about the approach, and the original implementation. Documentation to come.
