Vector

Implement a Vector class (or a set of functions) that models a Physical Vector. You should implement The four basic operations and a 'pretty print' function. Your Vector may be initialized in any reasonable way.

- Start and end points and direction - Angular coefficient and value (length)

Python

Implements a Vector Class that is initialized with origin, angular coefficient and value.
