class  IGESGeom_ConicArc
 defines IGESConicArc, Type <104> Form <0-3> in package IGESGeom
A conic arc is a bounded connected portion of a parent
conic curve which consists of more than one point. The
parent conic curve is either an ellipse, a parabola, or
a hyperbola. The definition space coordinate system is
always chosen so that the conic arc lies in a plane either
coincident with or parallel to XT, YT plane. Within such
a plane a conic is defined by the six coefficients in the
following equation.
A*XT^2 + B*XT*YT + C*YT^2 + D*XT + E*YT + F = 0
