Return a string made out of ASCII tablature representing a Note object or note string. Throw a RangeError if a suitable fret can't be found. 'tuning' should be a StringTuning object or None for the default tuning. To force a certain fingering you can use a 'string' and 'fret' attribute on the Note. If the fingering is valid, it will get used instead of the default one.
