Alpha Trees - Render massive forests, fast

[tweekazoid (Michal Hons)]

ok done

the issue was in my case repaired by changing main register() in alpha_trees:

def register():
    modules = get_current_level_modules(__file__, __package__)
    if sys.platform != 'win32':
        modules = list(reversed(modules))
    for module in modules:
        module.register()

Unix systems sometimes evaluate code backwards and this helped to eliminate missing Operator dependencies in my case
