Subject: Merging changes from 'stwcs_hdrlet' branch (r18787 - r13909) into
 trunk. This version of STWCS (0.9.1) provides support for headerlets based on
 'Headerlet Design' wiki document, and includes TEAL interfaces for all public
 headerlet functions. It also moves the TEAL interface for 'updatewcs' from
 'astrodither' to this package. The TEAL interaces have been included as a new
 'gui' sub-package in order to keep them separate from the remainder of the
 package's functionality.
