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

     This function implements Fisher's z-transform, which maps a
     correlation rho in (-1,1) to

                      0.5*log((1+rho)/(1-rho)).

_A_r_g_u_m_e_n_t_s:

   corrs: a vector of correlations in (-1,1).

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

     The return value is a vector of z-transformed correlations.
