I added the ability to display the parallel axes from the MultiCurve
plot either horizontally or vertically. Specifically, I replaced the
window mode WINMODE_AXISPARALLEL with the two modes WINMODE_PARALLELAXES
and VERTPARLALLELAXES. The mode is controlled by the MultiCurve plot.
I also changed all the instances of AxisParallel to ParallelAxes.
