/**
 * This is a simple implementation of a Block component. Block components are
 * very simple, and in reality do not differ much from the generic component.
 * Blocks are capable of storing an arbitrary content (string) and naturally have
 * their type set to <code>BLOCK</code>. Unlike the generic component, the content
 * of Blocks is required.
 * <br /><br />
 * <code>Components</code> are the basic units that can be displayed on
 * the screen. The main method <code>render()</code> which renders the component
 * on the screen.

     * @param string content This is an arbitrary string that will be printed,
     *  whenever the user calls the <code>render()</code> method. The parameter
     *  is required.
     * @param integer index The index of this component. The index has no semantic meaning:
     *  you can think of the index as 'level' of the component. Alternatively,
     *  the index could serve as means of distinguishing between components with
     *  the same type. Most often one would use the index in conjunction with
     *  the <code>getStylesForComponentType()</code> and
     *  <code>addStyleForComponentType()</code> methods.
     * @param optional object StyleCollections styles,... Zero, one, or more StyleCollection
     *  objects that will be added to the newly created Component. Warning, this will
     *  result in copying the objects instead of referencing them as using
     *  <code>addStyle()</code> would do.
