=item MainLoop

=item missing_colour

When selecting a colour using L<METHOD get_colour_for>,

is not defined, the default is 0.

=head1 METHOD plot_map

Plots the map on the existing canvas. Arguments are supplied
in a hash with the following keys as options:

The values of C<bmu_x> and C<bmu_y> represent The I<x> and I<y>
co-ordinates of unit to highlight using the value in the
C<hicol> to highlight it with colour. If no C<hicolo> is provided,
it default to red.

When called, this method also sets the object field flag C<plotted>:
currently, this prevents C<main_loop> from calling this routine.

See also L<METHOD get_colour_for>.
