Best model selection function

A data dredge function to select the best models given a global model (i.e. x ~ a + b + c). The function works through an exhaustive combination of parameters and outputs a dataframe where models are ranked by model selection methods, such as AIC or WAic.

Output includes:

• log-likelihood "LL";
• number of parameters "k";
• Akaike Information Criterion "AICc";
• the difference between the two AIC values being compared "∆AIc";
• Watanabe Akaike Information Criterion "WAic".
