if gene is a subclass of locus this means
that some locus, say locus aaa
is subclassified as a gene
subclasses in ace are simply an automatic sorting system inside
a class
hence Locus aaa has the same name as Gene aaa, since there is a single object
Keyset show the native names
-Title is for tree displays
however, you may alias any object so that 2 names will be used
ace file is
-A Locus aaa bbb
now aaa and bbb will be recognized
unfortunately aliases do not properly dump
so this info should be keppt preciously !
from then on aaa and bbb will be recognized names
an alternative is to have a separate class gene, XREF to locus,
but this is probably less good
