/**
 * The Accessor is used to get some basic data out of the game without having to request direct access to the game engine.<br>
 * It will also return things that are unmodified by the overriding systems (like getWailaStack).<br> 
 * Common accessor for both Entity and Block/TileEntity.<br>
 * Available data depends on what it is called upon (ie : getEntity() will return null if looking at a block, etc).<br>
