 * Simple task executor interface that abstracts the execution

 * <p>Implementations can use all sorts of different execution strategies,
 * such as: synchronous, asynchronous, using a thread pool, and more.
 *
 * <p>Equivalent to JDK 1.5's {@link java.util.concurrent.Executor}
 * interface. Separate mainly for compatibility with JDK 1.4.
 * Implementations can simply implement the JDK 1.5 <code>Executor
 * interface as well, as it defines the exact same method signature.
