Add Help Buttons

Throughout the app, there should be help buttons to display helpful information regarding the different fields. The contents of the help message should be stored in a Global object that allows for access across the app.

There should also be a quick walkthrough after creating a new account as well as access to review the help sequence through the settings page. This will likely come/be created during the writing of the report to document the app. Additionally, the Mac app will have help icons as well, so maybe the Apple Help HTML pages created for the Mac app can be used for the iOS app as well.
