* Algorithm: An int[][] of X/Z directions is created on static class

* (0,0) center and all (+-2, +-2) corners are omitted.
*
* handleBlock() returns a boolean, which is used for the sole purpose of
* switching between these two behaviors:
*
* (Call blockState "this log" for the below explanation.)
*
* [A] There is another log above this log (TRUNK)
* Only the flat cylinder in the directions array is searched.
* [B] There is not another log above this log (BRANCH AND TOP)
* The cylinder in the directions array is extended up and down by 1
* block in the Y-axis, and the block below this log is checked as
* well. Due to the fact that the directions array will catch all
* blocks on a red mushroom, the special method for it is eliminated.
*
* This algorithm has been shown to achieve a performance of 2-5
* milliseconds on regular trees and 10-15 milliseconds on jungle trees
* once the JIT has optimized the function (use the ability about 4 times
* before taking measurements).
