macbethChartCreate

 Create a data structure of the Gretag/Macbeth Color Chart reflectances

    macbethChartObject = macbethChartCreate([patchSize=12],[patchList=1:24],[spectrum={400:10:700});

 Create a scene of spectral reflectance functions of the Macbeth chart.
 The chart is coded as if you are looking at it with four rows and six
 columns.  The white surface is on the left, and the black surface is on
 the right.
 
 The numbering of the surfaces starts at the upper left and counts down
 the first column.  The white patch, therefore, is number 4.  The
 achromatic series is 4:4:24.

 To read the surfaces in the standard ordering used in image processing
 routines, like vcimageMCCLAB, use 

  list = [4 3 2 1 8 7 6 5 12 11 10 9 16 15 14 13 20 19 18 17 24 23 22 21]
  macbethChartOther(:,list) = macbethChart;
   
 The surface reflectance function information are contained in the slot
 macbethChartObject.data. It is possible to have spectral information
 between 370 to 730 nm.  That is the limit of the Macbeth calibration
 range.

 The default patch size is 16 pixels
 The default patch list is all 24 macbeth surfaces, though you may create
 a partial image.

 Examples:
    macbethChartObject = macbethChartCreate(16);

    spectrum.wave      = [370:10:730];
    macbethChartObject = macbethChartCreate([],[],spectrum);
