function LaTeXCode = LaTeXPlot(export_name, figure_handle)
% function LaTeXCode = LaTeXPlot(export_name, figure_handle)
% 
% LaTeXPlot exports the figure specified by figure_handle or uses gcf (if
% figure_handle is not set) to export the figure to export_name.tikz in 
% the current folder for use in LaTeX.  The necessary code for LaTeX is
% copied to your clipboard and exported to the screen if no output is
% provided.  If an output is provided, the LaTeX code is returned as
% LaTeXCode.
%
% Note: This function requires the use of matlab2tikz, which is available
% through the MATLAB exchange.  Don't forget to have
% 
% \usepackage{pgfplots}
% \newlength\figureheight
% \newlength\figurewidth
% % A setting that would be applied to all pgfplots
% \pgfplotsset{every axis/.append style={
%   max space between ticks=40pt,
%   scaled y ticks = false, 
%   scaled x ticks = false, 
%   y tick label style={/pgf/number format/fixed},
%   x tick label style={/pgf/number format/fixed},
%   compat=1.10
