Turned off HTTP 500 errors so we don't trigger the anti-intrusion system.
Fixed syntax.
Replaced 'tr//' with s//' which I understand much better.
Tweaked error message so that it's more understandable.
commented out Goloboff tree from menu

According to Rutger pre-processing won't complete because, in regard to
processing the tree, Rutger says "There was a script that did this, but
I don't see it finishing the goloboff trees before the heat death of
our solar system."
added some comments
removed greengenes tree from menu (not implemented)
Improved debugging in case of a blank tree being returned by Hadoop.

Added some other trees to test against.
Better debugging.
Improved debug message.
Updated tree2tabled with tolweb recompiled with underscores.
Restored 'tolweb' as a tree name.
Turning unpack_tabled.cgi back on so we can install the new tolweb tree.
Re-de-activating this code.
Undoing the hack I put in for tolweb; it's no longer needed. Also: more tests.
