function [D,S] = perform_circular_fast_marching_2d(W, start_points, center_point, options, H)

% perform_circular_fast_marching_2d - launch the Fast Marching algorithm for circular propagation.
%
%   [D,S] = perform_circular_fast_marching_2d(W, start_points,center_point,options, H);
%
%   'W' is the weight matrix (the highest, the slowest the front will move).
%   'start_points' is a 2 x k array, start_points(:,i) is the ith starting point .
%   'center_point' is a 2 x k array, it is the center around the flow will turn.
%
%   Optional:
%   - You can provide special conditions for stop in options :
%       'options.end_points' : stop when these points are reached
%       'options.nb_iter_max' : stop when a given number of iterations is
%          reached.
%   - You can provide an heuristic (typically that try to guess the distance
%       that remains from a given node to a given target).
%       This is an array of same size as W.
