<code>intersectWhere</code> determines if the Ray intersects a triangle
defined by the specified points and if so it stores the point of
intersection in the given loc vector.

@param v0
           first point of the triangle.
@param v1
           second point of the triangle.
@param v2
           third point of the triangle.
@param loc
           storage vector to save the collision point in (if the ray
           collides)  if null, only boolean is calculated.
@return true if the ray collides.
