User needs collections

The current draft is based on the user needs identified in the gap analysis and road-map from coga: Their tables identifies the user needs, how it can be met via normal HTML and where and how personlization can meet the need better. See https://rawgit.com/w3c/coga/master/gap-analysis/table.html

However we may wish to add more.

Other places we should look at are:

• https://w3c.github.io/personalization-semantics/user-settings (note settings are a bit different)
• http://w3c.github.io/apa/fast/#inventory-user-needs
• https://www.w3.org/wiki/WebSchemas/Accessibility
• SC 36 (Andy please add)
