function createSpaghettiPlot(y,t)
   This function creates a ``Spaghetti'' plot from functional data that are given in cell
   array form. 
 
  Input 
  y:          1*n cell array, y{i} is the vector of measurements for the ith
             subject, i=1,...,n.
  t:          1*n cell array, t{i} is the vector of time points for the ith
             subject, at which corresponding measurements y{i} are taken,
             i=1,...,n.
  
  Example:
  createSpaghettiPlot(y,t);   %Plot the original data, where y contains the responses and t contains the corresponding time points
  yy = FPCA(y,t);
  y_predOrig = getVal(yy, 'y_predOrig');
  createSpaghettiPlot(y_predOrig,t);    %Plot the predicted functions as obtained from the PACE fitting procedure
 
  % Plot the first 20 subjects from the original data and the fitted functions for direct comparison
  subplot(1,2,1);
  createSpaghettiPlot(y(1:20),t(1:20));
  subplot(1,2,2); 
  createSpaghettiPlot(y_predOrig(1:20),t(1:20));
