std_logic is set to change switch to next direction and change iswitch2 to
switch changing the direction to opposite side.
std_logic is also set to change istate to emergency situation.
std_logic_vector is set to change idirection to variable that accept the
assigned direction.
light_direction is modified to 4 for adding emergency situation.
