-// Interfaces to helper functions used for generating trees

-/*
-Note that all of these functions must generate the same tree image for the same input (x, y, z, seq)
- - cStructGenTrees depends on this
-To generate a random image for the (x, y, z) coords, pass an arbitrary value as (seq).
-Each function returns two arrays of blocks, "logs" and "other". The point is that logs are of higher priority,
-logs can overwrite others(leaves), but others shouldn't overwrite logs. This is an optimization for the generator.
