/**
 * Evaluates the given string as if it was a template

 * Although this plugin is kind of optimized and will
 * not recompile your string each time, it is still not
 * a good practice to use it. If you want to have templates
 * stored in a database or something you should probably use
 * the Dwoo_Template_String class or make another class that
 * extends it
 * <pre>
 *  * var : the string to use as a template
 *  * assign : if set, the output of the template will be saved in this variable instead of being output
 * </pre>
