Batch function

This function will create duplicates that seriously mess up the db. The process for detecting terms that already exists needs to be much better. Also, if you delete a taxonomy term it will reset the content type to none. You then have to reset the content type. After doing this, if you run a batch process it will not analyze what nodes you already have, instead it will duplicated them if they already exist. Then if you delete the duplicate nodes it will of course delete your taxonomy terms. The batch process is currently very DANGEROUS and should be used with caution or you will lose a lot of your taxonomy terms! I learned the hard way.
