MusicSheetMaker song_creation as a list of self.methods?

[jmmelko]

I think it is possible to make the song_creation method a pure list of calls to self.methods, using only the recipient as the input parameter. To do, this 2 steps:

• Create a retrieve_song_notes methods, which searches for the latest query about notes and get the notes out of it. Tricky part: handle files.
• Make create_song a loop iterating over a dictionary of self.methods, calling them one by one, with recipient as the only parameter
• Add an n integer or 'string' input parameter in create_song so we can skip to the call of method of the nth method or referenced by 'string'

Then, the code in the cog would become:

for i in range(len(maker.continue_song)):
    q = maker.continue_song(recipient=player, method=i)
    execute(q)
