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

     maps a bounded parameter x onto the real line according to
     y=log((x-xl)/(xu-x))), with xl < x < xu. If this constraint is
     violated, an error occurs. x may be vector

_U_s_a_g_e:

     ftrf(x, xl, xu)

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

       x: a numeric vector 

      xl: a numeric vector of same length as x with x > xl 

      xu: a numeric vector of same length as x with x < xu 

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

     returns numerical vector of transforms
