Restrict users from seeing another users' calendar

Requested by Atikamekw, a First Nations client with a need to keep information confidential among the users as they are part of a small community where everyone knows everyone. There are also MYLE users working in youth protection in cases of sexual abuse.

The ''Note Restriction'' feature is activated in this environment, where the note is hidden from all users except for those who are granted access.

As admin staff, I want a similar feature to also restrict employees from seeing specific calendars unless they are granted access. Ex. an employee works exclusively in sexual abuse cases. If another employee sees clients' names on her calendar, the employee can deduce information about the client.
