Web-enabled control of user rights of elements and collections of elements

As a Solution builder

I want to be able to control user rights to elements, collections of elements and (possibly) themes through the MAE interface

So That I can push responsibility to set rights to create, read, edit and delete singular elements and collections of objects to element or collection owners (rather than having to have specialised people with access to MBA to do this).

Benefits 

1. Greater flexibility in terms of who can be given control of access rights to elements.
2. "The right people doing the right thing" - as an architect and solution builder, I do not want to be part of a whispering game or pushing away functionality from the people who ought to control access.

Acceptance Criteria 

1. Being able, through MAE controls, to set user rights for single elements and collection of elements, both for single people or groups.
2. Managing of "meta rights", i.e. being able to set which users/groups who can do what.
