Updating generic crop parameters?

[samsrabin]

I met with @linniahawkins yesterday, and she wondered whether the parameters for the generic crops (1-indexed 15 and 16, c3_crop and c3_irrigated) should be updated based on her new c3_non-arctic_grass parameters. The generic crops don't currently match c3_non-arctic_grass, but it's hard to know whether that's intentional. I.e., were they intentionally parameterized at some point, or instead were they initially a match of c3_non-arctic_grass but then got left behind as the latter evolved?

Tagging @danicalombardozzi and @slevis-lmwg, who may know more about the history here.

I'm pretty sure that originally c3_crop and c3_non_arctict_grass were the same. We may be able to go back far enough to find a paramfile where they were the same and then figure out when they diverged, though I don't know if we would know why...
