App development on the Prime

[CheshireChris]

Application variables (created with AVars) preserve their value between runs of the app. They are "permanent" data (stored in a file) rather than only existing while the app is running. In the case of the astronomy app I'm writing, I want to store the user's geographical location in app variables so they can be entered once the first time the app is run, and will then be stored for future runs. Once an app variable has been created it's used like any other variable, but the special "AVars" function is used to initially create it.
