Extends one class with another class and optionally overrides members with the passed literal. This classalso adds the function "override()" to the class that can be used to overridemembers on an instance.<p>This function also supports a 2-argument call in which the subclass's constructor isnot passed as an argument. In this form, the parameters are as follows:</p><p><div class="mdetail-params"><ul><li><code>superclass</code><div class="sub-desc">The class being extended</div></li><li><code>overrides</code><div class="sub-desc">A literal with members which are copied into the subclass'sprototype, and are therefore shared among all instances of the new class.<p>This may contain a special member named <tt><b>constructor</b></tt>.
