    Grandparent class for plotting

    registration, lookup, and init
    of modes.

    To create a new plot mode,
    inherit from PlotModeBase
    or one of its children, such
    as PlotSurface or PlotCurve.

        Tries to return an appropriate mode class.
        Intended to be called only by __new__.

        mode_arg
            Can be a string or a class. If it is a
            PlotMode subclass, it is simply returned.
            If it is a string, it can an alias for
            a mode or an empty string. In the latter
            case, we try to find a default mode for
            the i_var_count and d_var_count.

        i_var_count
            The number of independent variables
            needed to evaluate the d_vars.

        d_var_count
            The number of dependent variables;
            usually the number of functions to
            be evaluated in plotting.

        For example, a Cartesian function y = f(x) has
        one i_var (x) and one d_var (y). A parametric
        form x,y,z = f(u,v), f(u,v), f(u,v) has two
        two i_vars (u,v) and three d_vars (x,y,z).
        NzETo use unregistered plot mode %s you must first call %s._init_mode().z7%s can only plot functions with %i dependent variables.zA%s cannot plot functions with more than %i independent variables.TFz-PlotMode argument must be a class or a string)
