ANY: create easy annotation generation methods for params objects

[rmflight]

Instead of depending on the Category package to get the proper annotations, we need to have a general example of getting the annotations. For example, using an EntrezGene database (e.g. org.Hs.eg.db), we could generate the GO annotation this way:

allGO <- as.list(org.Hs.egGO2ALLEGS)

# filter, and get description

Supplying this as an annotation object to the params creator would then allow it to filter the annotations down to just those that have genes from gene universe. This would also be rather generic, it should work for EG, probes, yeast, and other weird things like drosophila and arabidopsis. All that is needed is the database file, and the "GO2ALL" method. Or the select method, as shown here
