           Summary: Adding .upper() and .lower() methods to the Seq object

             nThis:


As part of making the Seq object more string like (Bug 2351), it would be nice
to support the .upper() and .lower() methods.

Doing this elegantly will require different case versions of the alphabets (see
Bug 2532), perhaps by adding (private) upper and lower methods to the Alphabet
object itself.

Alternatively, we can handle this without adding new Alphabets by mapping the
fixed case IUPAC alphabets to case-less generic alphabets.
