2D implicit curve

• plotimplicit(f(x,y),x,y) draws the graphic representation of the curve defined by the implicit equation f (x, y) = 0 when x (resp y) is in WX-, WX+ (resp in WY-, WY+) defined by cfg,

• plotimplicit(f(x,y),x=0..1,y=-1..1) draws the graphic representation of the curve defined by the implicit equation f (x, y) = 0 when 0 $\leq$ x $\leq$ 1 and -1 $\leq$ y $\leq$ 1

It is possible to add two arguments to specify the discretisation steps for x and y with xstep=... and ystep=....
