/**
* ABOUT
*
* The template.php file is one of the most useful files when creating or modifying Drupal themes.
* You can add new regions for block content, modify or override Drupal's theme functions,
* intercept or make additional variables available to your theme, and create custom PHP logic.
* For more information, please visit the Theme Developer's Guide on Drupal.org:
* http://drupal.org/node/509
*/
/**
* MODIFYING OR CREATING REGIONS
*
* Regions are areas in your theme where you can place blocks.
* The default regions used in themes are "left sidebar", "right sidebar", "header", and "footer", although you can create
* 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.
*/

* Declare the available regions implemented by this engine.
*
* @return
* An array of regions. The first array element will be used as the default region for themes.
* Each array element takes the format: variable_name => t('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 hexatrope_. For example:
*
* original: theme_breadcrumb()
* theme override: hexatrope_breadcrumb()
*
* See the following example. In this theme, we want to change all of the breadcrumb separator links from >> to ::
*

/**
* CREATE OR MODIFY VARIABLES FOR YOUR THEME
*
* The most powerful function available to themers is the _phptemplate_variables() function. It allows you
* to pass newly created variables to different template (tpl.php) files in your theme. Or even unset ones you don't want
* 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
* (and any other derivative node template file, like node-forum.tpl.php), comment.tpl.php, and block.tpl.php
*
