// Topics: Geometry, Circles, Tangents
// Description:
// Computes 2d lines tangents to a pair of circles in 2d. Returns a list of line endpoints [p1,p2] where
// p2 is the tangent point on circle 1 and p2 is the tangent point on circle 2.
// If four tangents exist then the first one the left hand exterior tangent as regarded looking from
// p1 is the tangent point on circle 1 and p2 is the tangent point on circle 2.
// If four tangents exist then the first one is the left hand exterior tangent as regarded looking from
// circle 1 toward circle 2. The second value is the right hand exterior tangent. The third entry
// gives the interior tangent that starts on the left of circle 1 and crosses to the right side of
// circle 2. And the fourth entry is the last interior tangent that starts on the right side of
