RivuletExpDataProcessing changelog 09.02.2013

rivuletProcessing.m
- cleaned the code of RivSurf function
 - calculation of the IFACorr simplified with better use of matrix
   operations - memory is not the problem, the computational time is
- added calculation of the ARhoCorr, density of the gas-liquid
  interfacial area surface, integral, for the whole rivulet
- added calculation of the ARhoL, the dependence of the size of the
  interfacial surface area on the plate length coordinate (z in the
  programs)
Note: The results are saved correctly and also, they are displayable
from the quick data overview (postProcPlotting NEEDS TO BE MODIFIED).
However, the changes have to be made in naming the variables and the
resulting plots.

normDistParsFit.m
- cleaned the code, added comments and help - to be finished

To Do:
- modify postProcPlotting.m to work with interfacial area densities
- finish cleaning the code on normDistParsFit.m

RivuletExpDataProcessing changelog 11.02.2013

normDistParsFit.m
- finished cleaning the code and writing in the comments. if there will
  be some spare time, the comments and helps should be expanded

postProcPlotting.m
- made changes to allow display of the surface densities data
Note: because of the student conference, I had to change the independent
      variable for all the plots from liquid dimensionless flow rate to
      liquid mass flow rate. if there will be enough time, I should
      modify the code of postProcPlotting.
      another change to the postProcPlotting function were made,
      especially to the displayed point sizes and font sizes. it would
      be usefull to extract these plot properties to one place to be
      changed easily (even from the code)
- now, the postProcPlotting.m can display rivulets surface density along
  the plate, and ARhoCorr
- code was a little bit cleaned up, after the student conference madness
To Do: - modify or get rid of the axis changing (gas ffactor vs liquid
         flow rate
       - possibly replace/expand this feature by easy changing of
         independent variable - M/dot{m}/FFactor
       - check the axes !! - g/s <-> kg/s

rivuletProcessing.m
- the local surface densities are very close one to another, there is
  need to test, if it is due to an error, or if the calculation system
  has flows
  - no, even with replacement of the local a by cummulative a, the
    results are almost the same
  - found and corrected a bug which caused this - bad conversion from
    cell to double, this algorithm goes along the first non-singleton
    dimension, if I need to create a matrix n x m from the cell of size
    n x (1 x m), it is necessary to transpose it at first
- added DRAWNOW to the code to repetively redraw the GUI -> i should
  stop it from freezing
- changed the way sliced variables are saved - now the function can
  handle the NaNs and ingnore them in statistical variables calculation
To Do: - check the calculation assumptions for the sirface area density
         because different results were obtained for almost the same
         measurements
