 * Defines {@code alias} for {@link org.apache.ignite.lang.IgniteClosure} by extending it. Since Java doesn't provide type aliases

 * concise code in cases when readability won't be sacrificed. For more information see {@link org.apache.ignite.lang.IgniteClosure}.
 * @param  Type of the free variable, i.e. the element the closure is called or closed on.
