                    averageVector()

Averages this collection of vectors into one VectorDivisible point as the mean location of each vector.

Returns VectorDivisible.zero, if the collection is empty.

let vectors = [
    Vector2D(x: 3.0, y: 4.3),
    Vector2D(x: -2.0, y: 2.3),
    Vector2D(x: 2.0, y: 6.9)
]

print(vectors.averageVector()) // Prints "(x: 1.0, y: 4.5)"
