Reviewed r12844. Changeset seems fine, thanks.
It should be noted that tree creators (grow and esp. full) should not use the maximum depth limit set in the problem but should use a smaller depth limit for initialization instead. Otherwise, we would produce huge trees in the initial population.

r12844: Adapted tree creators to work with the same depth restriction as the PTC2 (excluding the root symbol).
