'''

Generates a TSV file to be uploaded to Amazon's seller central.

It has three input sources:

 1. The catalog database which it reads from the local database.

 2. FeatureValues.xls which is generated using the FeatureValueExtractor

  script in the ContentStore project.

 3. ItemNumbers.xls which is fetched from Nilesh to get UPC/EAN

 of all handsets since Amazon is adamant that they'll not accept data w/o it.

Once the CSV file is generated, a header should be added to it.

@attention: The columns and their order in the featurevalues.xls can

change depending on the object model. As such the output should be 

checked manually.
