Simple annotation/text example

[GHSoCoder]

A first hello,

and many thanks for all your efforts!

I'm testing VexFlow/EasyScore and looking for an simple example (EasyScore
preferred), just one bar with:

• clef treble
• just a quarter note, no time signature
• annotation/text above/below the note

My aim is the genertion of labels for the keys of my (music) keyboard
with note name and MIDI numbers.
