Attempting to fix u = 0 case.
u=infty, fixed labeling on component.
Sketched out proof of Q^2.

Just started proof of P^2.
Computed contribution at u=0 to P_00^2.
Fixed defn of g in u = infty result, where P_ij lie.
Moved self-intersections result.

Moved to *after* D_P . P' results.
Added to proof of P_00^2.
Minor fixes.
Finished proof of self-intersections.
Finished self-intersection exposition.
