      More improvements to MARS.  This eliminates situations where we have linear dependence in the basis functions.  Previously that was causing convergence failures.

      Add r2converge method to PCA.  This generates a table showing the convergence of R^2 as a function of the number of principal components.

      This checkin adds functionality to the new PCA approach that was in Alessandro's PCA approach: · 5754eaaa

        1. outlier detection.  This is in the newly added "preprocessing" directory.
      
        2. Principal variables.  This is a new method in the PCA class.
      
      These two options don't have all of the options that Alessandro's versions had, but they have most of the essential parts.

      I deleted the "find" from " bkterm(find(bkterm<=0)) = 0; " because when I opened this file in my MATLAB there was a message saying that it is going to be a little bit faster if we write it like " bkterm(bkterm<=0) = 0; " .
      
      @BasisFunction/represented_orders:
      It is a function to store the orders of the used dimensions in a parent basis function in a vector.
      
      @UnitBasis/represented_orders:
      the represented oreder function for the case that the parent of  basis function is a unit basis.
      
      calculate_r2:
      I added the value of the predicted y into input arguments of this function in order to avoid repeated calculation of the predicted y in each time that we call calculate_r2 .
      
      compare:
      I changed the place of 13th line with 15th one because we need the value of the predicted y in calculate_r2 function in order to avoid recalculate it .
      
      create_new_basis:
      I added A and ypred in the input arguments and also output arguments in order to prevent some unnecessary calculation and make the code runtime shorter.
      
      regress:
      I change the method of calculating the value of A matrix. in this way each time we should just calculate the last two new columns and add them to our previous A matrix. It makes the runtime more less. In this case we need A as an input and output in function.
      
      refine:
      I added some initial values for A and ypred and added them as input and output of the create new basis function in order to keep their values.
