## Converting Between Multiple Coordinate Systems

The coordinate system classes are designed to support arbitrarily complex coordinate systems as well as to allow easy conversion between systems. The actual job of transforming between systems is done by one or more `CoordTransform` objects, each handling a specialized transformation. To engage a `CoordTransform` object, one can ``attach'' it to a `CoordinateSystem` object. By attaching multiple `CoordTransform` objects, one effectively can ``daisy-chain'' them together to produce more complicated transformations. They can be attached during the `CoordinateSystem` object's construction or anytime after, say, by request of the user. `CoordTransform` objects can also be used independent of any `CoordinateSystem`.

  - `getInAxes(), getOutAxes()`
  - `determineConstraints(Metadata in, boolean forwards)`
  - `init(CoordinateSystem csys, boolean forward, int[] axisIndexList)`
  - `getMetadata(Metadata in, boolean forward, int[] axisIndices)`
