Classroom and Student Table DB cleanup tasks

[patudom]

• Create a script that daily runs a script to find new students in db who have used the "default 5 galaxies" measurements and put them into the IgnoreStudents table.
• Add Class "status" to Classes table - "seed" "real good data" "real bad data" "test good data" "test bad data"
• Figure out which classes in the Classes table are garbage test classes and should be added to the IgnoreClasses table.
  • Anything that is "real bad data" or "test bad data" should get ignored.
• For "real good data" and "test good data" classes, query sizes. If classes have N < 15, then treat them as "small" and add 12 random students to those classes. Added note: Should the "class size" we query here be the total number of students in the class, or the total number of students with complete measurements? Probably the latter?
• Going forward, figure out how to handle unpadded large classes where only a small number of students have completed all 5 galaxy vel & dist measurements. (Otherwise, they would effectively be a small class datawise even though they are a large class in total student numbers).
