 lyngby_lzit_main     - Main function for Lange-Zeger estimation

       function Result = lyngby_lzit_main(P, Y, 'PropertyName',
          'PropertyValue'); 

       Input:    P   Paradigm
                 Y   Normalized data matrix

       Property: Iterations   { 90 } The number iterations
                 MinChange    { 1e-4 } Stopcriterion for the
                              iteration
                 StepSize     { 1 } Gradient descent stepsize
                 Theta1Init   { 10 } Initialization of theta1.
                 Theta2Init   { 2 } Initialization of theta2.

       Output:   Result    Estimated parameters in matrix 3xN 
                           [beta; theta1; theta2]'

       Fitting of a gamma kernel for each voxel in the Fourier domain.
       This function makes some initialization before iterating: 
       for every voxel calling lyngby_lzit_algo to do the actual fitting.
