I'm in the midst of testing this code.  It seems to work too well.  In the
past, $gene->exons() would return the exons in the order put in to the
gene.  I by default sort them and return them in order.  This breaks some
of the tests.

Should I 
(a) un_default the sort of exons, or 
(b) change the tests, or 
(c) something else?
