Specs
perp_prod( a, b ) finds the perpindicular product of one vec2 with another vec2.
a is the first vec2.
b is the second vec2.
The perpindicular product is the magnitude of the cross-product between the two vectors.
It returns a float of the value (a<sub>x</sub>b<sub>y</sub> - b<sub>x</sub>a<sub>y</sub>).
