function [bigc,val]=getcontour(c)
% [bigc,val]=GETCONTOUR(c)
%
% From a contour matrix, gets the contours
%
% INPUT:
%
% c       A contour matrix out of CONTOUR or CONTOURC
% 
% OUTPUT:
%
% bigc    A cell array with the coordinates of these contours
% val     A vector with the contour values
%
% EXAMPLE:
%
% for index=1:length(val); plot(bigc{index}(1,:),bigc{index}(2,:))
% hold on; end
