Fixed #94

pt_from_pt_equiAngle arguments:
this: 'origin Surface'
originSurface_phi: a domain value from 'origin Surface'.
targetSurface: the Surface of which we want to find the domain value (phi, theta) whose codomain value has the same angle (in relation to origo in the euclidian space. Not in relation to 'AngleSpace') as the codomain value of originSurface_phi has in the origin Surface.
