Deletion of Leland Smith

Comment: Smith single-handedly developed what is arguably the best music typesetting program SCORE (software), and warranted a three page obituary in a major academic journal.  A Google on 'Leland Smith SCORE' brings up a non-trivial amount of notable mentions, as it does Google Books (per |BEFORE).  I consider these to satisfy the notability guidelines

Comment: Between his SCORE (software) (especially) and his book (which I added to the article; I didn't find reviews but it is held by 36 libraries according to WorldCat; notable also as the first completely typeset music book), I'm seeing  shaping up.  That's bolstered by his work as a composer -- I found a https://www.nytimes.com/1973/11/14/archives/music-to-plug-in-or-punch-out-or-just-maybe-to-see.html brief nytimes review of a performance of a piece of his, for example.  The CMJ obit helps support GNG.  I think that the combination forms a solid keep case
