--------------------------------------------------------------------------
Small script for plotting the smoothened generalized velocities and accelerations
--------------------------------------------------------------------------
File Description :
This script upon on clicking on one of the plots in the KRPlotHandles.Plot_IK_UiPanel
panel will be activated and will plot a detailed graph including the
generalized coordinates, velocities, and accelerations associated with the
initial plot.
