It is more than a problem of namespace collisions in some areas.  In
the futures markets, there are *no* standard for the mnemonic/"symbol"
used for the various markets.  The exchange might use one symbol, data
vendors another, and different brokers will use another one still.

For example, my company's database shows that the Australian 3-year
Gov't Bond contract traded on the Syndey Futures Exchange is
alternatively known as HT, YS and YTT.  Orange Juice futures are known
sometimes as OJ and sometimes as JO, depending on who you are talking
to.  I could go on and on...

This is a pain in the ass in a number of different applications:
processing historical price data from different data vendors, parsing
electronically transmitted info from brokers, etc.

IMHO, the gnc_commodity API should show some flexibility in this area,
rather than just mapping each commodity to one allegedly canonical
