Variables names of a GADSdat object, a all_GADSdat object or a eatGADS data base.
Details
If the function is applied to a GADSdat object, a character vector with all variable names is returned. If the function is
applied to a all_GADSdat object or to the path of a eatGADS data base, a named list is returned. Each list entry
represents a data table in the object.
