Threshold function representing growth limitation by temperature.

Run grass growth simulations using a grass growth model based
on ModVege (Jouven, M., P. Carrère, and R. Baumont "Model Predicting
Dynamics of Biomass, Structure and Digestibility of Herbage in Managed
Permanent Pastures. 1. Model Description." (2006)
<doi:10.1111/j.1365-2494.2006.00515.x>). The implementation in
this package contains a few additions to the above cited version of ModVege,
such as simulations of management decisions, and influences of snow cover.
As such, the model is fit to simulate grass growth in mountainous
regions, such as the Swiss Alps. The package also contains routines for
calibrating the model and helpful tools for analysing model outputs and
performance.
