Previous versions of the timber mod caused trees to instantly decapitate,
if a log is thrown at a tree, or you grow a tree close to wood logs from
a previous decapitation.  That meant if you dropped or chopped a log, any wood
logs near by would suddenly be harvested!  That was bad news for players build
wooden houses!

This version does not have that problem, as the effect can only be initiated
by using a special item, the 'Golden Timber Axe'. In other words this version
will not effect normal game play.   Just don't throw it at trees too close to
your log cabin.

How you use it is you are given (perhaps as a reward) a special
               ' Golden Timber Axe '
This axe is quite OP in its own right as it insta-mines wood when used
normally. In that case however it would wear out as even with strong
unbreaking it will only get a few hundred uses.

Now if you throw the special axe next to a tree, the tree will disintegrate
into a shower of logs, harvesting it completely in moments. After a moment the
axe and all the logs just harvested will become inert, and chain reaction
stops. This does not effect the axes durability.

Unfortunately Acacia and Dark Oak Tree logs are different to all other logs,
and as such will not work (unless you double the number of command blocks
used). Thanks a lot Mojang!

Setup - Once only
  /scoreboard objectives add Timber dummy

Give a special axe to a player (adjust to suit)

   # Golden 'Timber' Axe - Efficiency X Unbreaking X
   # The efficiency is important as it can not be enchanted in game
   /give @p minecraft:golden_axe 1 0 {display:{Name:Timber},ench:[0:{id:32s,lvl:10s},1:{id:34s,lvl:10s}]}

   # Unbreakable version (unbreakable state is hidden)
   /give @p minecraft:golden_axe 1 0 {display:{Name:Timber},ench:[0:{id:32s,lvl:10s},1:{id:34s,lvl:10s}],Unbreakable:1,HideFlags:4}


Fast Fill clock...

   # Identify Special Axe - make it a 'Timber Entity'  (do not use 'Set')
   /scoreboard players add @e[type=Item] Timber 0 {Item:{id:"minecraft:golden_axe",tag:{display:{Name:"Timber"},ench:[0:{id:32s,lvl:10s}]}}}

   # Increment Timber count - so Timber effect will timeout (20 ticks)
   # NB: this timeout is also in all following commands.
   /scoreboard players add @e[score_Timber=20] Timber 1

   # Find Log Entities near 'Timber' entity and make them 'Timber' entities
   /execute @e[score_Timber=20] ~ ~ ~ /scoreboard players add @e[r=1,type=Item] Timber 0 {Item:{id:minecraft:log}}

   # Destroy any log block near a 'Timber' entity
   /execute @e[score_Timber=20] ~1 ~ ~ detect ~ ~ ~ log -1 /setblock ~ ~ ~ air 0 destroy
   /execute @e[score_Timber=20] ~-1 ~ ~ detect ~ ~ ~ log -1 /setblock ~ ~ ~ air 0 destroy
   /execute @e[score_Timber=20] ~ ~ ~1 detect ~ ~ ~ log -1 /setblock ~ ~ ~ air 0 destroy
   /execute @e[score_Timber=20] ~ ~ ~-1 detect ~ ~ ~ log -1 /setblock ~ ~ ~ air 0 destroy
   /execute @e[score_Timber=20] ~ ~1 ~ detect ~ ~ ~ log -1 /setblock ~ ~ ~ air 0 destroy

Redstone Notes:

* The Axe is very OP, and is only given to players who has harvested a full
  single chest of wood logs, or 1728 logs (via a 'Achievements Mod' ).

* I generally expand the setblock tests to include ALL diagonally upward
  neighbours around the 'Timber' entity - total 9 testing command blocks

* You can expand it further to detect/setblock all neighbours.
  That is 8 on same level and 9 in layer above.
  This allows it to handle the branches of Jungle and Large Oak trees.

* The above can be made to work for Acacia and Dark Oak Trees
  by duplicating the 'Find Log Entities' and 'SetBlock Destory' commands to
  look for minecraft:log2 entities and blocks. I have also done this.

* I do not include a test for any log block below the enity. I did not feel
  It was necessary, and actually can save you trouble if you drop the axe on
  a log floor.

* It would have been better if all the setblock commands could be replaced by
  a single fill-destroy command. Unfortunately that command does not let you
  specify a 'replacement' block, so just destroys everything in the area,
  including leaves (which is not bad) but also stone, dirt and whatever else
  tree may be close to the tree, including a sloped ground.   Arrgghhhh....
