sensorFilterType

Assign single letter and other parameters to a filter based on the filter name

   [letter, number, plotColor] = sensorFilterType(filterName)

  The letter and other parameters assigned here are used for plotting and
  related activity of a color filter. 
  
  Several letters are reserved  to describe filters.  These are used in
  the routine sensorColorOrder (e.g., red, green, cyan). Other first
  letters are not reserved or known in color order.  These are given the
  label 'o' for and a colormap entry of gray (.5,.5,.5).

 Example

    [letter, number, plotColor] = sensorFilterType('rName')
    [cfaOrdering, cfaMap] = sensorColorOrder;
    displayColor = cfaMap(number,:)
