09-10-07 New options to plot and process outputs from multiple runs based on the format introduced (09-05-18)

Originally only the mean values or the mean values of accepted runs could be viewed. With the new option the user can select a specific run number to be represented in the chart. Two buttons are shown in the dialog window when a chart has been created. The New Curve (1) button adds a new variable to the current chart with a new run number compared to the last plotted variable. The New Run (2) button change the last variable plotted to represent a new run in the sequence of multiruns.
