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

     Find values at specified timepoints from curves specified as all
     corners of step functions.

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

     timepoints(w, times)

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

       w: a list containing the estimates, with points for all corners
          of the step function.  (Usually created by cuminc.) Each
          component in the list contains the estimate for a different
          group. Each component has components giving times, function
          estimates, and variances (see cuminc) 

   times: vector of times where estimates are needed 

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

     A list with components 

    $est: a matrix of estimates of the subdistributions with a row for
          each component in `w' and a column for each time

    $var: a matrix giving the corresponding variances.
