Practice Coach

The practice coach would ask me what I want to practice (I could select multiple options from a list). Then I specify how much I want to practice, and how long each practice session is. The coach then reminds me when it is time to practice. I can snooze it if I don't have the time right then. The coach doesn't just remind me though, it will also suggest which topic to practice, e.g., scales, rhythm, intonation, self-recording, playing a song. Depending on what I had set up at the beginning. Would be dope if I could be reminded not only in the app but also on my Soundbrenner Core!

Changed the title from "Practice Coach" to "App: Practice Coach"

Merged "Coach for practice" #3
