The pathPrefix argument is passed to molvizTopper so that relative urls will be correct.
Given that molviz.js resides in the molviz directory, any file calling this function from the molviz directory
will need to pass an empty string. But files calling it from elsewhere need to pass a string that will give the 
urls in the correct relative locations.
