Adds multiple axes to plots using addaxis.m. Automatically adjusts axes to accomodate as many axes as you want.
Add more plots to any added axes with addaxisplot.m
Add y-labels to any of the axes with addaxislabels.m
All plots zoom together. A small modification to the zoom function allows all of the added axes to update with zoom.
zoom modifications for R11.1 and R14SP2 are included.
Usage is almost exactly like the plot command, see the help for addaxis.m for examples.
