* 
	 * @param name
	 *            the name (or description) of the main task
	 * @param totalWork
	 *            the total number of work units into which the main task is
	 *            been subdivided. If the value is 0 or UNKNOWN the
	 *            implemenation is free to indicate progress in a way which
	 *            doesn't require the total number of work units in advance. In
	 *            general users should use the UNKNOWN value if they don't know
	 *            the total amount of work units.
