    Performs the enhancement. It is possible to invoke this method concurrently, but when doing so make sure no two enhancement tasks are invoked on the same class in parallel: the Enhancer implementations are not required to guard against this.
    
    Parameters:
    
    className - The name of the class whose bytecode is being enhanced.
    
    originalBytes - The class's original (pre-enhancement) byte code
    
    Returns:
    
    The enhanced bytecode. If the original bytes are not enhanced, null is returned.
    
    Throws:
    
    EnhancementException - Indicates a problem performing the enhancement
