/*
The init method of the supersleight object takes three optional parameters:
1. String path to the transparent gif file. Note this path is relative to the actual document, not the JavaScript document.
2. Boolean value to apply relative positioning to anchor and input elements. Pass false to leave the elements as they are.
3. String ID of an element to limit SuperSleight's operations to.
To call SuperSleight from a script, use the run method of the supersleight object. This method takes the same three optional parameters as the init method.
