Incircle! 1 for GoldenJ

Ryan Hirst
As an experiment, I shall try to find the Incenter of a circle, a number of different ways. Attempt 1.
Calculus is like a little master key for geometric problems. The update script in t carries out the procedure suggested under "?", with one adjustment: a damping term has been added. Without it, D will orbit a solution indefinitely (try setting k to 0). Note that the condition BD = BF = BG is strict. GGB only stops when it judges the three lengths to be equal. But I haven't proved anything about the incircle! Hum.
