singleton pattern doesnt work. SingletonPattern.py

The Singleton pattern doesn't work with new style classes (which includes Python 3.0) I've tested using version 2.5.4 (used object in my class definition) and in version 3.0 and saw the same results. Finally the backticks are deprecated in 3.0 and should be replaced with repr().

**program output **(obviously your will differ)
