* Reindent TimeSeries classes * Fix spacing in time series tests * Remove trend tests where current is nil I think if we've gotten this far with a nil value for current, there's a data integrity problem. If we allow this, we'll have to be very defensive in our code. Best to raise and fix early. * Reindent Money class * Refactor TimeSeries artifacts * Use as_json in TimeSeries * Bring back tests for trends where current is nil * Bring back trend test * Correctly enumerate trend test * Use favorable_direction for trend_styles helper * Make trend public in TimeSeries::Value * Allow nil current values in trends I think I might've gotten it wrong before, nils might appear in trends if values are unavailable for snapshots * Clean up TimeSeries::Trend * Skip trend values same class validations if any values are nil * Refactor Money * Remove object parsing in TimeSeries::Value We're only every passing hashes
