[+] VectorsGiven 2 vectors A and B, this calculates: * Length (magnitude) of A = A * Length (magnitude) of B = B * Sum of A and B = A + B (addition) * Difference of A and B = A  B (subtraction) * Dot Product of vectors A and B = A x B A ÷ B (division) * Distance between A and B = AB * Angle between A and B = θ * Unit Vector U of A. * Determines the relationship between A and B to see if they are orthogonal (perpendicular), same direction, or parallel (includes parallel planes). * CauchySchwarz Inequality * The orthogonal projection of A on to B, proj_{B}A and and the vector component of A orthogonal to B → A  proj_{B}A
Also calculates the horizontal component and vertical component of a 2D vector.
