     A color scheme is a  collection of colors that can be used to
     provide a particular style or theme. A color scheme has colors for
     the background and the labels/annotations, and a pallette of color
     values that can be used to display different values within the
     scheme. There are different types of schemes for displaying
     different effects or styles. For example, there are continuous or
     divergent schemes.

     Objects can be created by calls of the form 'new("ColorScheme",
     ...)'. Typically, we retrieve schemes using 'getColorSchemes'.

_S_l_o_t_s:

     '_c_o_l_o_r_s': A list containing the different colors for the values in
          the color scheme. Each element is an object of class
          'Color-class', currently 'RGBColor-class'.

     '_b_a_c_k_g_r_o_u_n_d': Object of class '"Color"'. This is used as the
          background color for displays using this scheme. 

     '_a_n_n_o_t_a_t_i_o_n_s': Object of class '"Color"'. This is used to color
          labels, etc., i.e. decorations on plots.

     '_c_r_i_t_i_c_a_l_v_a_l_u_e': Object of class '"integer"'  

     '_d_e_s_c_r_i_p_t_i_o_n': Object of class '"character"'. A string giving a
          human readable description of the characteristics of this
          color scheme.

     '_t_y_p_e': Object of class '"integer"'. An integer and name
          describing the particular type of the color scheme. These are
          currently qualitative, sequential, divergin and spectral. The
          integer value is used internally. Generally, R users will
          only refer to these by the name of the type.

     '_s_y_s_t_e_m': Object of class '"integer"'.  A name and integer value
          identifying how the colors are represented. Currently, we are
          only using RGB. 

     '_n_a_m_e': Object of class '"character"'. A name for identifying the
          color scheme.

_M_e_t_h_o_d_s:

     No methods defined with class "ColorScheme" in the signature.
