Function vector:dot
Returns the dot product of two vectors.
Syntax	vector:dot(vector vect)
Returns	vector
Part of	ComputerCraft
API	vector

Example
Creates a dot product of two vectors and prints the resulting vector.
Code	local a = vector.new(1, 2, 3) local b = vector.new(4, 5, 6) local c = a:dot(b) print(c) --32

Example
Code to recreate the function. Gives insight into what the function does.
Code	local a = vector.new(1, 2, 3) local b = vector.new(-1, 2, 5) local c = ((a.x * b.x) + (a.y * b.y) + (a.z * b.z)) --c = 18

In the case of dot products, a:dot(b) will equal b:dot(a).
