DefineCircle[p1, p2, p3] Function calculates the center, normal and radius of the circle defined by the three spatial points p1, p2, p3. The function returns with {{Ox, Oy, Oz}, {nX, nY, nZ}, r} of the circle, where {nX, nY, nZ} is the normal vector of the plane defined by p1,p2,p3 points. 
DefineCircle[p1, p2, p3] In case of planar case, when p1,p2 and p3 points are defined with 2 dimensional lists, the function calculates the center and the radius of the circle. 
Calculate points of the circle by rotating P1 point around the normal vector anchored by the origin of the circle
