ENH: Incorporating suggestion from Jelle Feringa to support an unzipped directory of the tvtk_classes so code completion works properly in pydev.  This change implies that if you create a directory called tvtk_classes and unzip the tvtk_classes.zip into this directory it will use the unzipped code.
