Find the circle that passes through 3 non-collinear points. Uses a fast analytical method based on finding the intersection of the bisectors of 2 of the line segments. Avoids divide by zero errors in all cases. Faster than determinant methods.
Tested under MATLAB 7.5 but should work on previous versions
