Allow creation of TradingEnvironment to specify a minimum date, so that
trading days, market opens, etc. can trimmed to a range more relevant to
the backtest.
This changes is with an eye towards storing all market minutes in the
trading environment, where storing values for much more than the
simulation range starts to become more costly.
Replace it by distinguishing between "Loadable" and "Computable".
This is useful because it's now possible to write computable terms that
don't require any inputs (e.g. an `Always` filter or an `Everything`
classifier).
Upgrade six 1.9.0 -> 1.10.0 in requirements.txt, and futures 3.0.3 ->
3.0.5, requests-futures 0.9.5 -> 0.9.7, and piprot 0.9.1 -> 0.9.6 in
requirements_dev.txt.
There was a comment in requirements.txt warning not to use
python-dateutil 2.4.0, which was necessary when we were using 2.3.x
and 2.4.0 was broken for us, but now we're using 2.4.2 which is fixed,
so the comment is no longer needed.
