I'm not sure that it will be acceptable to change the start year for this usecase, could you create a new usecase instead? 1852_cam_lt.xml perhaps

I've moved the new 1850_cam_lt.xml to leapyears_cam_lt.xml and reverted 1850_cam_lt.xml.
My push of these changes to my fork is failing with "The requested URL returned error: 500".
Should I push it somewhere else instead?

Why this change? Aren't these both leapyears?

Some of the external forcing files end in 2014. Since I'm changing the increment between the forecasts from 2 to 4 years I wanted to avoid problems from requesting a year that's beyond
the time span of those files. If that was too pre-emptive, I'll try a test with 2012.
