This file defines the seqRegion interface.

The seqregion package populates a data structure with all the information
about a particular DNA area. This package is the interface between the drawing 
code  and the underlying database engine. Different version of the code access
acedb directly via the BS and sMap interfaces, or a remote server via Fex.

The public part of the seqRegion datastructure is exposed to the
drawing code. This may not depend on any back-end data structures or types: 
No KEYS, classes or sMapInfos allowed.
