Processes discovery data and creates items for 500px-grab.

Unpack new response data into directory original, see the directory itself for examples. Run the following to get a list of photo identifiers from the responses:

cd original
python get_ids.py <responses>

where <responses> is for example AttributionLicense3-API-Sever-Responses.

An *_ids.txt file is then created. In the main directory run:

python generate.py <_ids.txt file> <num>

where <_ids.txt file> is for example the previously created original/AttributionLicense3-API-Sever-Responses_ids.txt and <num> is a number not yet used for item lists (also see the item lists that have been added to the tracker in ADDED).

A file containing an item list is now created. Add the file to the tracker. Move the file to the ADDED directory.
