-- WIP

-- [locate tree row]
-- look at direction of point B
-- move 2 forward
-- turn left
-- move 1 forward

-- LOOP !!
-- [chop tree]
    -- dig
    -- forward
    -- digUp & Up till no obstacle (count for every time went up)
    -- go COUNT down
    -- go 1 backwards
    -- replant
    -- turn right
    -- move 3 forward
    -- turn left
    -- check if obstacle ? continue loop : position next row and do again

-- [Clear inventory]
-- get to drop off station
for i = 1, 16 do
    turtle.select(i)
    turtle.drop()
end

-- [Refueling]
-- * get to refuel station
if turtle.getFuelLevel() < 5000 then

end

-- wait (for fuel efficiency, so the turtle doesn't waste fuel walking around ungrown trees
