*
* This container class collects sky regions objects derived from the
* GSkyRegion abstract class. These can be accessed from the access
* operator[] or through the at() method with index checking. Access to
* the region can be done from index or name, so the name of each region
* in the container has to be unique.
*
* The object can be initialised from a DS9 region file, and has load and
* save methods from/to a DS9 region file.
