            <Documentation>
                <UserDocu>Discretizes the curve and returns a list of points.
The function accepts keywords as argument:
discretize(Number=n) =&gt; gives a list of 'n' equidistant points
discretize(QuasiNumber=n) =&gt; gives a list of 'n' quasi equidistant points (is faster than the method above)
discretize(Distance=d) =&gt; gives a list of equidistant points with distance 'd'
discretize(Deflection=d) =&gt; gives a list of points with a maximum deflection 'd' to the curve
discretize(QuasiDeflection=d) =&gt; gives a list of points with a maximum deflection 'd' to the curve (faster)
discretize(Angular=a,Curvature=c,[Minimum=m]) =&gt; gives a list of points with an angular deflection of 'a'
                                    and a curvature deflection of 'c'. Optionally a minimum number of points
                                    can be set which by default is set to 2.

Optionally you can set the keywords 'First' and 'Last' to define a sub-range of the parameter range
of the curve.

If no keyword is given then it depends on whether the argument is an int or float.
If it's an int then the behaviour is as if using the keyword 'Number', if it's float
then the behaviour is as if using the keyword 'Distance'.

Example:

import Part
c=PartGeom2d.Circle2d()
c.Radius=5
p=c.discretize(Number=50,First=3.14)
s=Part.Compound([Part.Vertex(i) for i in p])
Part.show(s)


p=c.discretize(Angular=0.09,Curvature=0.01,Last=3.14,Minimum=100)
s=Part.Compound([Part.Vertex(i) for i in p])
Part.show(s)</UserDocu>
