Add a wiki

[RedstoneMedia]

Describe the feature you'd like

Add a Wiki to this GitHub Repo
This should include:

• How to Install the App
• The Main Page (How the layout works, How to access the settings)
• The Settings Page (How to add and remove courses, How to add/remove/switch profiles, What other options do)
• Sub Settings Pages (IServ Login options, Calendar options)
• FAQ (Common issues a user might have and how to fix them, Common features and how to activate them)
• Add a link to the wiki in the app

Before considering writing a wiki entry on the settings page, it should be considered to implement #15 first.
