public class Task
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<Task>

Default implementation of a divide and conquer task. The child tasks are used by the Computer to add input tasks during for later processing. Note: This class has a natural ordering that is inconsistent with equals.
