Music data output missing

[bobbicodes]

According to the readme the EDN data representing the song is output below Data-Robot. In the app currently however, there is no data nor Data-Robot.

This is not actually a complete lie - not only was it there at one point, but I had 2 different text boxes, one for EDN and one for MusicXML.

The best way to do this would be to add 2 buttons:

• Save: Download a file to the user's machine containing the EDN data for the song
• Load: Do the opposite. Validate data and swap into app-state.

While this is likely the optimal solution (and shouldn't be very hard), the way the system worked (before I broke it for whatever reason) was acceptable, where the song data simply sat in an editable text box that would update the app state upon validation. I think I want to just fix that first.
