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

     Create a scale for categorical colours.

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

     sccolour(plot = .PLOT, palette=1)

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

    plot: plot to add scale to

 palette: Color Brewer palette to use, see 'brewer.pal' for details. 
          Note that palette type is chosen automatically.

_D_e_t_a_i_l_s:

     Continuous variables will automatically be converted to
     categorical using 'chop_auto'.  You may want to use 'chop' to
     convert the values yourself for finer control.

     This scale is automatically added when you have colour in your
     list of aesthetics.  For finer control, you will need to set the
     scale yourself.  See the example for some ideas.
