Kenneth Moreland 2d30e6d45a Coordinate systems are stored as Fields
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.)
