[BioC] getting gene name from Entrez ID

[Francois Pepin]

Hi everyone,

Is there a way to map an Entrez ID to a gene symbol using the
bioconductor annotations? I would've expected that to be in the
xxxLLMappings annotations (I'm looking at human and mouse right now),
but they're not.

I'm matching a couple of lists from different sources (including custom
cDNA). Human-readable gene symbols make it a lot easier to deal with
those lists.

There are a couple of other ways of doing it, like biomart, so it's a
big problem. I was mostly curious if I missed anything there and see if
it might be a good idea to include it.
