Hmmm.  Now that I think about it, it should also be like a word processor.  The
user can position the mouse pointer between two residues and click on the left
mouse button to move the "cursor" to that spot.  He/she can even start typing
out letters from the keyboard, inserting residues as they type.  Hold down the
shift key and press left or right arrow keys and the residues are selected one
at a time.  The backspace key will delete residues on the left...you get the
idea :-)

Also, when a sequence is edited, we should keep a note in the XML what was added
or removed and where.  So, maybe a red vertical line will appear in a sequence
where something was...spliced.
