[Perform-Talk] DottedNotes — bidirectional braille ⇄ LilyPond/MusicXML translator (built out of my own frustration transcribing orchestral scores)

Thanks for recommending Liblouis, Ella.
After looking into both the BANA Braille Music Code and Liblouis, I 
think it's best for DottedNotes to only support Grade 1 UEB for now. It 
is the default for vocal lyrics according to BANA 35.1.1. Contracted UEB 
is only allowed for the narrow cases of chants, hymnals, school 
materials for grades 1-6, and upon user request (which still requires an 
uncontracted transcript to be included in the preliminary pages). 
DottedNotes converts individual musical scores a composer produces for 
performance or publication, and grade 1 is the rule BANA specifies to 
handle such material. However, DottedNotes does support parsing of 
accented letters in foreign words inside an otherwise-English lyric, 
since it's covered by UEB's bounded accent-modifier system. 
Incorporating the 150-table set from Liblouis would pull in a large 
external c-library dependency to cover contraction rules and 
per-language alphabets BANA doesn't sanction for DottedNotes' actual use 
case.
