32 * Methods for parsing free text properties on alignments and sequences. There
33 * are a number of ways we might want to do this: arbitrary regex. and an
34 * associated score name for the number that's extracted. Regex that provides
35 * both score and name.
37 * We may also want to : - modify description to remove parsed numbers (this
38 * behaviour is dangerous since exporting the alignment would lose the
39 * original form then) -
