_D_e_s_c_r_i_p_t_i_o_n:

     Functions to handle settings used by lattice.  Their main purpose
     is to make code maintainance easier, and users normally should not
     need to use these functions.  However, fine control at this level
     maybe useful in certain cases.

_U_s_a_g_e:

     lattice.options(...)
     lattice.getOption(name)

_A_r_g_u_m_e_n_t_s:

    name: character giving the name of a setting 

     ...: new options can be defined, or existing ones modified, using
          one or more arguments of the form 'name = value' or by
          passing a list of such tagged values.  Existing values can be
          retrieved by supplying the names (as character strings) of
          the components as unnamed arguments. 

_D_e_t_a_i_l_s:

     These functions are modeled on 'options' and 'getOption', and
     behave similarly for the most part.  The components currently used
     are not documented here, but are fairly self-explanatory.

_V_a_l_u_e:

     'lattice.getOption' returns the value of a single component,
     whereas 'lattice.options' always returns a list with one or more
     named components.  When changing the values of components, the old
     values of the modified components are returned by
     'lattice.options'.  If called without any arguments, the full list
     is returned.
