--  0.38 4/10/2014 2:00 AM
-- Changelogs
--  0.30 Rewrite of Everything
--  0.31 Extreme Bugs Fixing
--  0.32 Change Speed of Wide so wont look like program stop but if gravel in way it still works and change speed of Chest Code
--  0.33 Weird Chest Bug With Gravel Fix. So i change speed of chest to 1 sec i hope that fix it.
--  0.34 I think i found out want was making items on ground when turtle go back it cant bump it item so it on floor i now fix it.
--  0.35 Opps Fuel Code was worng
--  0.36 Fully Fixed Bug Where Items fall on ground it was Length Code
--  0.37 Change: Until High == Hc To Until High <= Hc so if number is not divible by 3 will stop when it past high limit
--  0.38 Change: Remove -5 on high so you can have you own hight
