Move students between groups manually and randomly

[hirokiterashima]

Changes

• Add Move Students Between Groups dialog
• In the new Move Students Between Groups dialog, added the following features:
  • show existing groups and allow teacher to choose one or more groups
  • move students between groups manually via drag and drop
  • move students between groups randomly via the shuffle button
  • remove one student from group using the "x" next to the student
  • clear all students from group using the clear all button next to the group name
  • cancel closes the dialog, and does not save changes
  • save saves all changes and closes the dialog

Test

• First checkout and pull from the "manage-groups" branch in SCORE-API, to make sure that you have the updated backend code for deleting and retrieving groups

  SCORE-API $ git checkout manage-groups
  SCORE-API $ git pull

• Verify that you can do all of the above grouping actions as a teacher

Closes #6

Thanks for the feedback!

Regarding randomization- what you described is the current behavior of the "shuffle" button. All the students in the class are shuffled and then assigned in round-robin order to the selected groups. Do you see a different behavior?

Good point about the UI. I can add a "Unassigned students" heading to the edit individual group dialog and improve the styles a bit.

Thanks for the clarification!

That is exactly what I was hoping for. I just had a misunderstanding based on the commit name that mod was being used to split the students into the groups (such as how WISE branching can work using the workgroupID).

Randomization and round-robin is sounds great. I'll do a little more thorough testing now.
