_D_e_s_c_r_i_p_t_i_o_n:

     a class that holds spatial lines

_O_b_j_e_c_t_s _f_r_o_m _t_h_e _C_l_a_s_s:

     hold a list of Lines objects; each Lines object holds a list of
     Line (line) objects.

_S_l_o_t_s:

     '_l_i_n_e_s': Object of class '"list"'; list members are all of class
          Lines-class

     '_p_r_o_j_4_s_t_r_i_n_g': Object of class '"CRS"'; see CRS-class

_E_x_t_e_n_d_s:

     Class '"Spatial"', directly.

_M_e_t_h_o_d_s:

     [ 'signature(obj = "SpatialLines")': select subset of (sets of)
          lines coordinates; value is a list of lists with matrices 
          .in -5

     _p_l_o_t '\signature(x = "SpatialLines")':  plot lines in SpatialLines
          object

     _l_i_n_e_s '\signature(x = "SpatialLines")':  add lines in SpatialLines
          object to a plot
