    25      This controller is responsible for two things:
    26
    27      1. Creating a new container
    28      2. Updating properties of an existing container
    29
    30      When creating a new container the result is NOT stored in the database.
    31      This happens later when the first event added to the container is saved to
    32      the database.
    33
    34      The reason for this behavior is that we don't want to have empty containers
    35      in the database. When updating the properties of an existing container the
    36      changes are stored in the timeline database.
