- "Creates an accidental rule that makes its decision based on the octave of the note
-and a laziness value.
-octaveness is either 'same-octave or 'any-octave and defines whether the rule should
-respond to accidental changes in other octaves than the current. 'same-octave is the
-normal way to typeset accidentals - an accidental is made if the alteration is different
-from the last active pitch in the same octave. 'any-octave looks at the last active pitch
-in any octave.
-laziness states over how many bars an accidental should be remembered.
-0 is default - accidental lasts over 0 bar lines, that is, to the end of current measure.
-A positive integer means that the accidental lasts over that many bar lines.
--1 is 'forget immediately', that is, only look at key signature.
-#t is forever."
