Add support to tree2table.pl to write to a single file

[eightysteele]

During pre-processing we're labeling nodes in a post-order traversal, then for each tip, saving the path to the root to a separate file.

As an option, can we add a command line switch to tree2table.pl that has it write results to a single file? It'll just make it easier to query the tree using a Cascalog tap.

@hlapp are you a Perl hacker? :)

I guess I look like one, right?

It was, but I dropped it.

Haha nice. OK, @rvosa, it's up to you and your sweet Perl skills. I'd make this change, but Perl scares me. Also it is soooo 1995. :)

This would be easy to do, so if there's a need for it I can do it.

There's a need for sure, so if you're game, let's do it.
