0028346: Function ProjectOnSegments of ShapeAnalysis_Curve returns only single solution leading to projection result far from optimal

Browse Source 
Subdivision of curve parametric interval based on deflection criteria is added for curve type OtherCurve in
Extrema_GExtPC.gxx. Algorithm of subdivision is implemented in Extrema_Curve(2d)Tool.cxx

New Draw command projpcurve for projection of point on CurveOnSurface is added in SWDRAW_ShapeAnalysis.cxx
projpcurve is modified to reflect "start parameter" in usage message and Draw help.
