Decide how users can write or modify stations

## Writing A New Station
The user should be able to start with a base (or maybe not even a base!) then be able to twiddle some knobs, maybe even paste in some text, even slide some sliders to manipulate the sound of the station, which they are hearing in realtime.

When the user finds a sound they like, they can "Save" the station.

## Modifying Existing Stations
- The user owns the station => modify the station.
- Unless the user doesn't want this? Maybe we should ask the user to make sure we know they want to overwrite the existing station.
- The user doesn't own the station => create copy of station w/ user as owner
