Functions to extract informations from BIOMOD.models.out, BIOMOD.projection.out or BIOMOD.ensemble.models.out objects

These functions allow the user to easily retrieve informations stored in the different biomod2 objects from the different modeling steps, such as modeling options and formated data, models used or not, predictions, evaluations, variables importance.
