xxsimGetPlotIDFromName

 xxsimGetPlotIDFromName - Find the corresponding plot ID for a certain window and plot name.

 Syntax: 
   retval = xxsimGetPlotIDFromName(windowName, plotName)

 Inputs:
   windowName = Either the window name or the window ID.
   plotName   = Either the plot name or the plot ID.
 
 Outputs: 
   retval = returns the ID of the plot or -1 if the plot could not be found. If a number was inserted for plotName,
            this number is given as return value.
 
 Examples:
   retval = xxsimGetPlotIDFromName('Window 1', 'Motor Torque')
   
     - retval now contains the ID of the corresponding plot or -1 if the plot window does not exist.
     - if the input would be numeric, retval will get that numeric value.
     - Note: The simulator should be open before calling this function.
