Create a Vector class with x and a y attributes that represent component magnitudes in the x and y directions.

Your vectors should handle vector additon with an .add() method that takes a second vector as an argument and returns a new vector equal to the sum of the vector you call .add() on and the vector you pass in.

For example:

>>> a = Vector(3, 4)
>>> a.x
3
>>> a.y
4
>>> b = Vector(1, 2)
>>> c = a.add(b)
>>> c.x
4
>>> c.y

Adding vectors when you have their components is easy: just add the two x components together and the two y components together to get the x and y components for the vector sum.
