_D_e_s_c_r_i_p_t_i_o_n:

     This function computes the fourth momemnt of a multivariate
     distribution. This result is used later in the mardia's test for
     multivariate normality

    data: The dataset containing the features of the mutlivariate
          vector which fourth momment will be computed

_V_a_l_u_e:

     Returns the fourth moment
