from debug display, remove streamer params, adjust sample calls
debug should be silent unless deb-p is true
turn debug display off
Each call to measure-pattern-test-parser should assume the next note or rest (or null, signalling the end)
is already in note-or-rest, so that func should not pull the next note in until it has processed it.

Adjust.
misnamed var: pat-el-one-note? should be called pat-val-one-note? everywhere
add a few more debug displays
