KIF syntax highlighting

From CS227B Wiki

You're encouraged to develop syntax files for your favorite editor.

Vim

You'll need to place two files into subdirectories of your VIMFILES directory. If you're on Linux, you'll put them in ~/.vim; if you're on Windows, you'll probably put them in c:\program files\vim\vimfiles.

" Identifiers are things which don't start with '?'.  I can't use \< and \> to
" separate words here because tokens with symbols are valid identifiers (e.g.
" '++').  So we have to special case the end-of-line case and whatnot.
"
" Right now, this allows identifiers which start with numbers, such as
" '123abc'.  I'm not sure if this is valid kif.
