changed table format, so that it is clearer and easier to use
First succesful merge with new table structure.
Changed expert table to "experts", grade to "grade", added metadata column to submissions table, removed old "params" declarations before sql queries.
Changed table names to be appropriately pluralized.
Added anonymized databases.
Added plotting code.
Added rawScore and rawScoreVector to grades table (changed createTables() to reflect this)
Implemented a slow weightsBIBI in the new schema.
Everything works but URL assignment and grade export.
Implemented grade report.
Comment reporting is functional, but very slow.
Added SWAPRsqlite.py
Bugfix: Made comment reporting report calibrated itemscores, not uncalibrated ones.
changed format of assigning URLs to grade in new table format
incorrectly reverted back to old SWAPRsqlite, changed functionality of finalize to match the new table structure
Added new URL assignment hotfix which works mostly through SQLite (lab 5 only)
Merged with Chris's alterations to SWAPRsqlite.py
Actually merged Chris's sqlite edits.
Dramatically sped up comment reporting; added practice and shown calibration videos to assignments
Updated grading system to use new weights table format.
