Also remove test that compares risk metrics batch to iterative,
since the 'iterative' calculations, replaced by the cumulative
calculations, will intentionally drift from the results in the risk
report due to annualization and other factors.
Work towards having separate calculations for the fixed periods versus
the cumulative/headline risk metrics.
Different sumbodules for each type should help make the calculations
type distinct and easier to find.
- Create different benchmark containers in performance
depending on emission rate.
- Add a minute close method which updates algorithm and
benchmark returns, and calculates the risk metrics
depending on those methods.
- Provide fake 0.0 values for annualized metrics like
sharpe, sortino, and information, until we figure out
how they should be treated in the context of minutely
calculation.
*NOTE* This does not fully work without the changes to the
simulation loop by @fawce
