Add weights to criteria tree — add_weights_to

This function takes weights from a data frame and adds them to the criteria tree. NOTE: the criteria tree is an R6 object. Therefore, when this function is called, the object will be changed in memory; i.e. the `$criteriaTree` `data.tree` object that is passed in `criteria` is passed by _reference_, not by value (the default for normal R objects).
