%GSP_BUNNY Create a graph of the stanford bunny
%   Usage :  G = gsp_bunny();
%
%   Output parameters:
%       G           : Resulting graph
%
%   'gsp_bunny()' creates a graph from the pointcloud of the Stanford Bunny model. 
%
%   Example:
%
%           G = gsp_bunny();
%           gsp_plot_graph(G);
