"Contracting the other rays in NE(X) for horospherical X"

I plan to continue from last time on contracting extremal rays in NE(X). This time, we will see how to contract the curve classes coming from walls in the coloured fan for X. So the plan is to touch on section 3.6 and then move to section 4.6 in Brion’s paper “Variétés sphériques et théorie de Mori”. If there is time, I will start the other material in section 4: flips.
