/**
* Template-Class
*
* With this class you can seperate the PHP-source from the design of your
* page. Just include this script and you are able to make objects, that
* contain the design of your page with some placeholder like: {placeholder}
*
* To fill them just act as follows:
* // Create the new Object
* $tpl = new Template("the_template_file.html");
* // Give the placeholder it's value / content
* $tpl->placeholder = "Hello World!";
*
* Remark that you set the value without the initiating and concluding chars,
* that are set in the globals "TEMPLATE_OPEN" and "TEMPLATE_CLOSE".
*
* You can also fill the placeholder with another template:
* // Bind a template to the placeholder
* $tpl->placeholder = new Template("another_template.html");
* // Access to the new placeholders
* $tpl->placeholder->placeholer_of_the_other_template = "foo";
*
* You can repeat this as often / "deep" as you want.
*
* Since version 1.2.0 you can add PHP-Scripts as an placeholder for your
* template. It's output (after execution) will be set for the placeholders
* value:
* // Add placeholder "foo" to template
* $tpl->foo = new Template("script.php");
*
* This has been added just to enhance the possibilities of this class. To use
* PHP as a placeholder is not the sense of templates!
*
* ATTENTION : Do NOT use ob_* within the PHP script, which shall be included.
* All PHP scripts are standalone-scripts. So if you want to use a variable from
* the mainscript you'll have to make it global in the template-script:
* global $var_name;
