* Source Code Highlighting
* The classes in this file are responsible for the dynamic @example, @filesource
* and {@}source} tags output. Using the phpDocumentor_HighlightWordParser,
* the phpDocumentor_HighlightParser retrieves PHP tokens one by one from the
* array generated by {@link phpDocumentorTWordParser} source retrieval functions
* and then highlights them individually.
* It accomplishes this highlighting through the assistance of methods in
* the output Converter passed to its parse() method, and then returns the
* fully highlighted source as a string

* to see if the member variable is defined to have 1 and only 1 class.
* If so, the $_pv_prev_var_type variable is set to this classname. When
