Computes the Akaike model weights for a list of HiSSE, MiSSE, and/or GeoHiSSE model fits.
GetAICWeights(hisse.results, criterion="AIC")A list of models (such as from MiSSEGreedy or just putting individual hisse runs in a list)
Which criterion to use, AIC or AICc (with correction for sample size)

Function computes the model weight from their AIC values using the formula:
“delta <- mod.AIC - min( mod.AIC )”
“AICw <- exp( -0.5 * delta) / sum( exp( -0.5 * delta) )”
Function will return vector of weights
