[GUSDEV] gene name semantics

[Steve F. <sfi...@pc...>]

folks-

when we load feature data, especially from genbank, it is possible that 
almost any feature might be associated with a gene name.

note, this is different than the feature being in a feature tree rooted 
at a gene feature.   fewer features are in those.

as it stands now, gus has two ways of dealing with this:
   1. some features have a view-column for name called 'gene'
   2. there is also the NAGene table (which should be renamed GeneName, 
because 'name' is its only attribute) and features can be linked to it via NAFeatureNAGene.


I propose that in 3.5 we:
   1. ignore the 'gene' attribute
   2. instead, only use the NAGene table to store gene names

In 3.6 I propose that we:
  1. lose the 'gene' attribute in all feature subclasses
  2. rename NAGene to GeneName and NAFeatureNAGene to NAFeatureGeneName

objections, encouragements?
