Talkwall UI issues
------------------


next / prev arrow in top bar causes task title text to move around

task list for teacher is too small.


Design for new Message Manager
------------------------------

immutable data set at message creation, not changed thereafter. shared with all on creation only:
---------------------------------------------------------------------------------------

MM type 1 = 'create'


	question_id:    { type: Schema.Types.ObjectId, ref: 'Question', default: null},
    	createdAt:      { type: Date, default: Date.now },
    	creator:        { type: String }, // nickname
    	origin: [
        	{
            		nickname:   { type: String },
            		message_id: { type: String, default: "" }
        	}
    	]


mutable by message creator only. not shared
-------------------------------------------

	edits: [
        	{
            		date:   { type: Date },
            		text:   { type: String }
        	}
    	]


mutable by message creator only. shared teacher and student
------------------------------------------------

MM type 2 = 'update'

	text:           { type: String, default: "" },
    	deleted:        { type: Boolean, default: false },

MM update type 1 = 'edit'
MM update type 2 = 'delete'


mutable by all. shared with teacher  (or just share to all?)
------------------------------------------------

MM type 2 = 'update'

        board:  {
            nickname: {
                xpos:   { type: Number },
                ypos:   { type: Number },
                highlighted: { type: Boolean, default: false }
            }
        }

MM update type 3 = 'position'


TO DO
=====


(done) Remove unnecessary redis calls

queue message 'position' updates on client, send just before poll.

assign database writes to a worker?

add 'toobusy' to server

add NewRelic to server

report call failures to console


*** Check that nicknames are unique!


->  Test that wall is removed from memory after inactivity
->  Test that clients stop polling after wall is removed
