* as many regions as you want.  Once declared, they are made available to the page.tpl.php file as a variable.  
* For instance, we use <?php print $header ?> for the placement of the "header" region in page.tpl.php.
* 
* By going to  the administer > site building > blocks page you can choose which regions various blocks should be placed.
* New regions you define here will automatically show up in the drop-down list by their human readable name.

/**
 * OVERRIDING THEME FUNCTIONS
 *
 *  The Drupal theme system uses special theme functions to generate HTML output automatically.
 *  Often we wish to customize this HTML output.  To do this, we have to override the theme function.
 *  You have to first find the theme function that generates the output, and then "catch" it and modify it here.
 *  The easiest way to do it is to copy the original function in its entirety and paste it here, changing
 *  the prefix from theme_ to zen_.  For example:
 *
 *   original:  theme_breadcrumb() 
 *   theme override:   danger4k_breadcrumb()
 *
 *  See the following example. In this theme, we want to change all of the breadcrumb separator links from  >> to ::

 *  to use.
 *
 *  It works by switching on the hook, or name of the theme function, such as:
 *    - page
 *    - node
 *    - comment
 *    - block
 *
 * By switching on this hook you can send different variables to page.tpl.php file, node.tpl.php
