Box-Cox transformation for geodata objects
Method for Box-Cox transformation for objects of the class
geodata assuming the data are independent.
Computes and optionally plots profile log-likelihoods for the parameter of the Box-Cox simple power transformation y^lambda.

This is just a wrapper for the function boxcox
facilitating its usage with geodata objects.
Notice this assume independent observations which is typically
not the case for geodata objects.
A list of the lambda vector and the computed profile log-likelihood vector, invisibly if the result is plotted.
