+/**
+ * Wraps up several useful functions for WordPress plugins and provides a method to separate
+ * display HTML from PHP code.
+ *
+ * <h4>Display Rendering</h4>
+ * The class uses a similar technique to Ruby On Rails views, whereby the display HTML is kept
+ * in a separate directory and file from the main code. A display is 'rendered' (sent to the browser)
+ * or 'captured' (returned to the calling function).
+ *
+ * Template files are separated into two areas: admin and user. Admin templates are only for display in
+ * the WordPress admin interface, while user templates are typically for display on the site (although neither
+ * of these are enforced). All templates are PHP code, but are referred to without .php extension.
+ *
+ * The reason for this separation is that one golden rule of plugin creation is that someone will always want to change
+ * the formatting and style of your output. Rather than forcing them to modify the plugin (bad), or modify files within
+ * the plugin (equally bad), the class allows user templates to be overridden with files contained within the theme.
+ *
+ * An additional benefit is that it leads to code re-use, especially with regards to Ajax (i.e. your display code can be called from
+ * many locations)
+ *
+ * Template files are located within the 'view' subdirectory of the plugins base (specified when registering the plugin):
+ *
+ * <pre>myplugin/view/admin
+ * myplugin/view/myplugin</pre>
+ *
+ * Admin templates are contained within 'admin', and user templates are contained within a directory of the same name as the plugin.
+ *
+ * User files can be overridden within the theme by creating a similar directory structure:
+ *
+ * <pre>/themes/mytheme/view/myplugin</pre>
+ *
+ * The class will first look in the theme and then defaults to the plugin. A plugin should always provide default templates.
+ *
+ * <h4>Display Parameters</h4>
+ * Also similar to Ruby On Rails, when you display a template you must supply the parameters that the template has access to. This tries
+ * to ensure a very clean separation between code and display. Parameters are supplied as an associative array mapping variable name to variable value.
+ *
+ * For example,
+ *
+ * array ('message' => 'Your data was processed', 'items' => 103);
+ *
+ * <h4>How it works in practice</h4>
+ * You create a template file to display how many items have been processed. You store this in 'view/admin/processed.php':
+ *
+ * <pre><p>You processed <?php echo $items ?> items</p></pre>
+ *
+ * When you want to display this in your plugin you use:
+ *
+ * <pre> $this->render_admin ('processed', array ('items' => 100));
