[galib] Tree genome and traversal.

[Laurent Steffan]

Hello Dan,

As I told you, I kept looking... :-)

In its present state, I believe, your program keeps visiting the same
node (presumably the root node) ad infinitum (well, as close to forever
as can be achieved with finite memory resources...). Your running out of
memory might explain the segfaults. I have underlined a possible correction.

	if(t.child()) ret << visitPost(t.child()) << " ";
	                                 ^^^^^^^
 	if(t.next()) ret << visitPost(t.next()) << " ";
	                                ^^^^^^

Do tell me whether this goes in the right direction.

Best regards,
Laurent
