(custom) Feeds tamper term hierarchy

This is a Feeds tamper module plug in to process hierarchical terms.
In your CSV, separate your terms by ">>" to describe a nested term.
For instance :
product>>book>>novel will assign the product to
-product
--book
---novel

If the terms tree doesn't exist, it will be created on the fly.

You can also combine this tamper with the existing "explode" action in feeds tamper, if you have multiple taxonomy terms to assign.

Post issue in the queue if you have problems.
