Coga Suggested Edit: Restructure the document to make it easier to follow

Comment from COGA Task Force.

Coga has found this document difficult to follow. We suggest the following restructure:

• Put sections 3, 4, 5 and 6 under a new section called "User needs and requirements". The structure would now look like:

1.Introduction
1.1 What are collaboration tools?
1.2 Distinctive features of collaboration tools
1.3 Collaboration tools and accessibility

2.User need definition

3. User needs and requirements
3.1 User needs for Real-Time co-editing
3.2 User needs for Annotations
3.3 User needs for Version control features
3.4 User needs for Notifications and Messages
