function [out]=mdsmap(long,lat,dataset,varargin)
% PURPOSE: This function links a map and mds analysis
%------------------------------------------------------------------------
% USAGE: out=mdsmap(long,lat,dataset,p,restarts,normflag,carte,label,symbol)
%   where : 
%           long = n x 1 vector of coordinates on the first axis
%           lat = n x 1 vector of coordinates on the second axis
%           dataset = n x p matrix of the variables to study
%           p = optional number of dimensions into which points are to be mapped
%               [default = 2].
%           restarts = optional number of restarts, after finding a new minimum stress,
%                    needed to end search [default=0].
%           normflag = optional boolean flag indicating that stress is to be normalized 
%                    to a range [0-1] if true (=1), or unnormalized
%                    sum-of-squared deviations if false (=0) [default = 0].
%           carte = n x 2 optionnal matrix giving the polygons of the edges of the spatial units
%           label = n x 1 optionnal variable used to label selected observations
%           symbol = * symbol=1 : selected spatial units are marked with a different symbol
%                    * symbol=0 : selected spatial units are marked with a different color only (default)
%------------------------------------------------------------------------
% OUTPUTS: out = (n x 1) 0-1 variable: selected spatial units are marked with a 1  
%------------------------------------------------------------------------
% MANUAL: Select points on the map or the mds plot by clicking with the left mouse button
%         You can select points inside a polygon: - right click to set the first point of the polygon
%                                                 - left click to set the other points
%                                                 - right click to close the polygon
%         Selection is lost when you click on the map
%         To quit, click the middle button or press 'q'
