 Plot function for Multidimensional scaling (SAMMON mapping)

 This function plots the results if SAMMON mapping, a multi-
 dimensional scaling method used for scaling multidimensional
 data to a lower dimension (normally to two or three dimensions).
 The initial data and the optimized data is shown and compared.

 Syntax:  samplot(DataLowOpt, DataLowStart, Labels, SamPlotOpt, FigName)

 Input parameter:
    DataLowOpt- Matrix of optimized low-dimensional data
                   every row corresponds to one data point 
    DataLowStart- same as DataLowOpt before optimization
                  (initialization of low-dimensional data)
    Labels    - Array of strings used for labeling data points  
    SamPlotOpt- Vector containing options for sammon mapping visu
                SamOpt(1): SamPlotNumber
                   number of the figure for sammon plot (used for 
                   multiple successive plots into different figures)
                   if omitted or NaN SamPlotNumber=1 is assumed

 Output parameter:
    no output
