goToPos func

-- goToPos Function. --
-- By Ninetainedo -- NoFake Dev Team --
-- Moves the turtle to xTmp, yTmp, zTmp considerating it is on 0, 0, 0. (Also turns the turtle to sideTmp considerating it is currently facing 0). --
-- Example :
--
-- .....
-- ...T.
-- .....
-- .D...
--
-- On this draw (Top view), the Turtle is the 'T', the destination is the 'D' and the turtle is facing on right (1)
-- I have to do goToPos(-2, -2, 0, -1, "szyx")
-- The last parameter represents the order the turtle has to move. In this case, it will move in this order : side, z, y, x
--
-- Axis are defined with turtle facing 0 :
-- x is forward
-- y is right
-- z is up
--
