  creates RGB color data for multiple 2D overlapping plots
 
  cMat = sw_multicolor(vMat, cMap, cLim, {nCol}, {flipud})
 
  Input:
 
  vMat      Matrix that contains the input 2D data, dimensions are
            [d1 d2 nPlot]. Where each plot has a dimensions of [d1 d2].
  cMap      Cell of colormap functions containing used for the different
            overlayed plots. For example:
            cMap = {@copper @gray}.
  cLim      Maximum and minimum values of the color map. Values in vMat
            smaller than the minimum and larger than the maximum will be
            shown with the minimum and maximum values in the colormap
            respectively. The dimensions of cLim is [1 2].
  nCol      Number of colors in the colormap. Optional, default value is
            100.
  flipud    If true the colormaps are inverted. Optional, default is false.
 
  Output:
 
  cMat      Matrix with equal dimensions to the input times three for the
            red, green and blue channels, dimensions are [d1 d2 3].
 
  Example:
            Plotting of two random matrices (dimensions are [100 100]) with
            red and blue colors:
                cMat = sw_multicolor(rand(100,100,2),[1 0;0 1;0 0],[0 1]);
                image(cMat);
