ckng's sandbox: Simple Access User

This module extends Simple Access module by allowing individual user be added to access groups.

Example use case:
- Users from the role student, but could be assigned to group classA, paperB, yearC, etc. to access different content. Using role for this will be a nightmare
- Occasionally temporary user such as tutor, or visiting lecturer

See original issue #1397074: Support per user and user group for additional patch needed for Simple Access.

Dependency:

• Simple Access
• ACL
