 /*
 How to use:
 1) Get dump of data as CSV format and name it 3pas.csv same directory as this script.
 2) Header fields in the CSV will be used as keys when destructing into JSON objects [ie: top row data should not have spaces or special chars]
 3) The two important column names are: 'name_legal_product' and 'domain'.
 4) There may not be a header named 'prefix'.
 5) 'name_legal_product' Will have it's data cleaned up a bit, so be prepared for it to change.
 6) This script tries to de-duplicate any data, so be prepared for many entries to go away if it finds a shorter one.
 7) This script will output a javascript file in the product_registry's data format.
