Adding Gaze raw data to the database

[paulosaurusrex]

Tested in Gauss by commenting out the eeg and fnirs lines to save time. Gaze data is correctly saved under /space/paulosoares/tomcat/tomcat.db.

@paulosoaresua - also, can you update the build_database_from_scratch.sh script to use chained commands with && so that the script exits with an error when any of the invoked Python scripts fail?

[paulosaurusrex]

@adarshp will, do, but notice master uses individual python calls. That's why I changed it after merging with it.

Also, I wrote this code based on the fnirs one. The foreign_key validation is also missing there (line 151 of the process_fnirs_data.py)

Re: individual python calls - that's a mistake on my part, I should have asked @eduongAZ to chain them.

Re: foreign key validation missing in process_fnirs_data.py - again a mistake on my part, can you add that line to process_fnirs_data.py as well?

[paulosaurusrex]

@adarshp No problem. Done.

Thanks @paulosoaresua !
