Updated sitemap and Hierarchy

Here is the updated system design. The new features are marked as green in the site map and are based on the user testing done by evan which collected features users would expect to find in the app. The new features are also based on the idea of personalising the app to someone. Two new features added which ties in with this theme is suggested gems based on gems you have saved and suggested friends based on your friends and saved gems.
The idea is the app starts making suggestions to you based on your activity inside the app and thus makes the experience more tailored to you.

The hierarchy stands at essential features and desirable features. The essential features are the basics of the app which cannot be lost and they are represented as orange and yellow in the site map. Desirable features are more broad than the basic version but are not essential to the basic app functionally. These would preferably be done on a grander scale when the app is developing further, they re represented as green in the site map.
