Updated rainfall-runoff models

Just a note for anyone who’s using the Hymod or HBV rainfall-runoff models. The previous versions were very specific to the paper I was doing, and thus not as useful or general as they could have been. Several people requested cleaned-up versions, so they’re now hosted separately on Github: Hymod and HBV. I removed the previous repo (titled “rainfall-runoff-models”) to avoid confusion.

Let me know if you have questions about running these, or feel free to submit a pull request!
