To add a dimension in a star_query object, we have to define its name and a
subset of the dimension attributes. If only the name of the dimension is
indicated, it is considered that all its attributes should be added.

# S3 method for star_query
select_dimension(sq, name = NULL, attributes = NULL)Arguments
- sq
A
star_queryobject.- name
