Deprecate "print..." methods, rename to respective "format..." counterparts

[Godin]

From a user point of view : I expect that methods, whose name starts with "print" ( e.g. ParseTreeUtils.printNodeTree ), would really print something to standard output, whereas this is not the case. So maybe would be better to rename them into something like "toString..." or "format..." ?

I agree, "format..." would probably have been a better name.
However, I don't think the benefit of breaking existing code just for this name change is worthwhile...

[Godin]

Why not simply introduce new methods, but keep previous for the several releases with annotation deprecated, so to let users migrate ?

Alright.
Thanks for raising the issue!
