% k = CurvatureEstimation(list,b,f)
%
% inputs,
% list : A M x 2 list of line points.
% fn: The number of forward points that were chosen to calcute.
% bn: The number of backward points that were chosen to calcute.
%
% outputs,
% Ei : M x 1 Curvature values
% thetai:M x 1 angle values
% Example
% [Ei,ti]=CurvatureEstimation(test,4,4);
