Represents a "factory" which can manufacture an additional auxiliary
coordinate on demand, by combining the values of other coordinates.

Each concrete subclass represents a specific formula for deriving
values from other coordinates.

The `standard_name`, `long_name`, `var_name`, `units`, `attributes` and
`coord_system` of the factory are used to set the corresponding
properties of the resulting auxiliary coordinates.
