=cut
sub new { my $pkg = shift;
    my ($left, $top, $direction, $length) = @_;

    my $self = $pkg->SUPER::new($left, $top, $direction, $length);

Return the turned direction ("left"/"right") or "" if no

=cut
sub possiblyTurnRandomly { my $self = shift;

    if((rand() + .0001) < $self->probabilityTurnRandomly) {        #0.0001 to come above 0, so we can have a 0% chanse of turning
        $self->oDirection->turn( my $direction = $self->randomDirection() );

        #If this turn puts us into a wall the next move, it's not worth it, turn back
        if(! $self->oValidLocationAfterMove()) {
