In Curve: Rearranged for speed. arc_length_fun is now a property of Curve. If it is not supplied, it is computed via the derivative and spline fitting. Switching to the arc length parameterization is much faster now. The new stuff can be tested with testArcLength.m (which should be deleted after that).

% cell2vector accepts a column cell array of column vectors and returns a columnvector
% with the input concatenated. It also returns the number of elements in each vector.
%   cv -- column cell array with column vectors
%   v  -- vector of the concatenated vectors
%   n  -- number of elements in each vector before concatenation. Can be used with vector2cell().
function [v, n] = cell2vector(cv)
    v = [];
    n = zeros(length(cv),1);

    for i = 1:length(cv)
        n(i) = length(cv{i});
        v = [v; cv{i}];
    end
end
