RivuletExpDataProcessing changelog 04.02.2013

postProcPlotting.m
- the code of distunguishable_colors.m function was removed because
  the function was made standalone

normDistParsFit.m
- ability to change number of cuts made along the rivulet (and fitted)
  was added, going from pixel to pixel is useless - waves + random
  noise + high computation time
