circle_fit (by Matrix inversion)

Really simple but robust circle fit

You are now following this Submission

much simpler circle fit method by using matrix inversion. We formulate the circle equation as follows:

x^2+y^2 = ay+bx+c

find a,b,c using matrix inversion to minimize RMSerror
xo = b/2
yo = a/2
r^2 = c+a^2/4+b^2/4
