Timeline controller

[theory-of-evrth]

Write timeline controller to fetch a particular timeline by id, check if the current user can view it, and if yes, pass the following parameters to the view:

• timeline start and end date, and overall width (empty function for now, just call it from Timeline Model)
• $nodes of this timeline
• title

Indications

• Don't edit models or views
• return timeline.blade.view
• test with : a public timeline, a private timeline, a private timeline where the current user is the owner
