function plotxppaut(file_name,C_Us,Lt_Us, N_plot)
%PlotXppaut
%Plot bifurcation diagrams in Matlab that have been saved by XPPAUT
%
%How to use:
%In AUTO (XPPAUT) click-->File--->Write Pts
%and save your bifurcation diagram in a .dat file
%In Matlab command window type: plotxppaut 
%Select .dat file saved by AUTO
%A bifurcation diagram will be plotted
%Cutomize the plot using Matlab figure editor
%Or edit program parameters to suit your needs--very useful for those who
%plot lots of bifurcation diagrams
