-- More trees!  2013-04-07
--
-- This mod adds more types of trees to the game
--
-- Some of the node definitions and textures came from cisoun's conifers mod 
-- and bas080's jungle trees mod.
--
-- Brought together into one mod and made L-systems compatible by Vanessa
-- Ezekowitz.
--
-- Firs and Jungle tree axioms/rules by Vanessa Ezekowitz, with the 
-- latter having been tweaked by RealBadAngel, most other axioms/rules written
-- by RealBadAngel.
--
-- License: WTFPL for all parts (code and textures, including those copied
-- from the the old jungletree and conifers mods).
