Many objects can produce other objects,
like a segment has an orthogonal segment
or a circle has its parametric curve.

This decorator makes a copy of the parameters 
of the old object to the new one.

EXAMPLE

Suppose the following in the class 'circle'

@copy_parameters
def parametric_curve(self,x):
    # compute the parametric curve 
    return curve

'circle.parametric_curve(x)' will return a parametric
curve with the same parameters as the initial circle. 
Like color, dashed, style, etc.

def phystricks.src.Decorators.sort_and_assert_real ( f )

The function Intersection has to return only points with real coordinates and have to sort these points.

This leads to code duplication because we create the point list in several different manners (with 'return' between them) depending on the passed parameters.
