	)

compute the actual "standard" spiral, starting with curvature 0

Parameters

s	run-length along spiral
cDot	first derivative of curvature [1/m2]
x	resulting x-coordinate in spirals local co-ordinate system [m]
y	resulting y-coordinate in spirals local co-ordinate system [m]
t	tangent direction at s [rad]
