first cut at reducing memory footprint of AABox
removed center from AABox to further save memory
some size comparison debugging
make voxelnode population statistics static members instead of per node
added old style voxelnode for size comparison
removed dead code
next round of voxelnode size improvements
type squish
first cut at really getting _children UNION to work
implement support for three children encoding
implement support for three children encoding
make offset bounds match 20 bit storage
added ifdefs for HAS_AUDIT_CHILDREN and added more memory tracking stats
make population stats use public getters and private member variables
cleanup dead code

cleaned up some printf's to qDebug's
Merge branch 'master' of https://github.com/worklist/hifi into voxelnode_memory_savings
add guards to prevent runaway reaverageVoxels(), added stats to see if 4 children could be packed internally
