/**
 * <p>Thrown to indicate an incomplete argument to a method.
 * This exception supplements the standard <code>IllegalArgumentException</code>
 * by providing a more semantically rich description of the problem.</p>
 * 
 * <p><code>IncompleteArgumentException</code> represents the case where a method takes
 * in a parameter that has a number of properties, some of which have not been set.
 * A case might be a search requirements bean that must have three properties set
 * in order for the method to run, but only one is actually set.
 * This exception would be used in place of
 * <code>IllegalArgumentException</code>, yet it still extends it.</p>
 * 
 * <pre>
 * public void foo(PersonSearcher search) {
 *   if (search.getSurname() == null ||
 *       search.getForename() == null ||
 *       search.getSex() == null) {
 *     throw new IncompleteArgumentException("search");
 *   }
 *   // do something with the searcher
 * }
 * </pre>
