* define the operation.

 * <p>
 * Operations determine their ability to execute, undo, or redo according to the
 * current state of the application. They do not make decisions about their
 * validity based on where they occur in the operation history. That is left to
 * the particular operation history.
 * </p>
 * <p>
 * Note: This class/interface is part of a new API under development. It has
 * been added to builds so that clients can start using the new features.
 * However, it may change significantly before reaching stability. It is being
 * made available at this early stage to solicit feedback with the understanding
 * that any code that uses this API may be broken as the API evolves.
