Creational Pattern (1)

Why i did it? 
I had to create a creational pattern and in this case i found the Factory method to be the one. where i created an interface for creating objects in a super class, but allowing subclasses to alter the type of objects that will be created.
How i did it?
I created a new interface class in #init for location to implement creational pattern  and the interface for location class is missing so i just added an interface class and serialized the location into a dict.
