Deletion of William Toy

Comment: There's a little non-trivial personal coverage of him in Derman's ''My Life as a Quant'' but not enough by itself for |general notability. All the rest of the coverage that I can find of him merely mentions his name as one of the creators of the Black–Derman–Toy model, a significant accomplishment but |only one thing. His #C1|academic citation record shows huge citations for that one thing but not much else, and his co-editorship of ''The Handbook of Equity Derivatives'' isn't enough for |notability as a book author. No merge because the other information about him in this article isn't relevant for the redirect target
