A test tree image

The current test tree is above. Node labels indicated by letters, node_id from the database indicated by numbers. This image is mainly for me to reference later when working with phyexort and phymod. I added the ability to include the database node_id in PhyExport so that it is easier to reference a given node by the identifier it has in the database.

PhyMod: Delete Query Available

A version of PhyMod that can do a delete query is now available from the project SVN. I ended up using the nested set values after tinkering with the transitive closure data. I will probably recode the SQL in these to avoid using nested SQL. The delete query is simply a cut at the command line where a paste is not indicated. The code will count the number of records that will be deleted from the tables and warns the user before wreaking havoc.
