I have added a new plugin to the fov_plugins package, which I hope will eventually become obsolete. It adds some missing scripting functionality to krpano, which does not immediately fit in with any of the other plugins. In my opinion, these functionalities are essential for krpano, so I hope they will eventually find their way into krpano itself.

Currently the plugin adds a for-loop and an absolute value method. Other methods may be added to the plugin as needed.
