teal_data utilsIn teal we need to recreate the teal_data object due to two operations:
we need to append filter-data code and objects which have been evaluated in FilteredData and
we want to avoid double-evaluation.
we need to subset teal_data to datanames used by the module, to shorten obtainable R-code
.append_evaluated_code(data, code).append_modified_data(data, objects)
modified teal_data
(teal_data)
(character) code to append to the object's code slot.
(list) objects to append to object's environment.
Due to above recreation of teal_data object can't be done simply by using public
teal.code and teal.data methods.
