Allow facilitators to view and remove reflections

[ArchdukeTim]

Issue - Enhancement

As a facilitator I want to be able to moderate reflections that have been submitted, and be able to remove them before making all reflections visible to the entire group. One reason I might want to do this is if I deem a reflection inappropriate, rude, etc. The reflections should still remain anonymous.

Acceptance Criteria (optional)

Facilitators can:

• View reflections in the think stage
• Delete reflections in the think stage
• Cannot see who created an anonymous reflection

Estimated effort: 15 points
