% inputs and outputs are similar to those defined in surf2mesh
%
% if method='cgalpoly', s2m will call cgals2m and keepratio should be a
% structure (as the 'opt' input in cgals2m)
%
% input default values:
%       method: if ignored, iso2mesh uses surf2mesh ('tetgen') to do the
%               tetrahedral mesh generation
%       regions,holes: if ignored, iso2mesh assumes both are empty
%
% -- this function is part of iso2mesh toolbox (http://iso2mesh.sf.net)
