Step 1

A vector is an object that has a length (or magnitude) and a direction and it cannot be expressed by a single number. In physics, vectors are commonly used to represent forces, velocities, accelerations, and other quantities. In this project you are going to build a vector space, a set in which a series of operations is defined between the elements in that set. You'll learn all the details very soon. For now, start the project by declaring an empty class named `Vector`.
