Update DBStorage and FileStorage, adding two new methods:
A method to retrieve one object:
Prototype: def get(self, cls, id):
cls: class
id: string representing the object ID
Returns the object based on the class and its ID, or None if not found
A method to count the number of objects in storage:
Prototype: def count(self, cls=None):
cls: class (optional)
Returns the number of objects in storage matching the given class.
If no class is passed, returns the count of all objects in storage.
