Previously, `DataSet` managed `CoordinateSystem`s separately from `Field`s. However, a `CoordinateSystem` is really just a `Field` with some special attributes. Thus, coordiante systems are now just listed along with the rest of the fields, and the coordinate systems are simply strings that point back to the appropriate field. (This was actually the original concept for `DataSet`, but the coordinate systems were separated from fields for some now obsolete reasons.)
