Lists of n-tuple reals

Some algorithms dealing with curves can be made more efficient if image coordinates are not recorded as a chain of points (x, y), but as part of an array. In such case, use one of the Flist, Flists, Dlist, Dlists objects above. These types can more generally be used to handle any list of n-tuple reals, the case of points in the plane corresponding to n = 2. As for curves, Dlist and Dlists are the counterpart of Flist and Flists : the only difference between them is that values are of type double instead of float.
