Set Neomake to use the local project's eslint when available for javascript files
Must already have neomake set up. This will automatically set eslint as a maker on top of setting its executable path for Neomake. Using vim-plug:
Plug 'jaawerth/neomake-local-eslint-first'
This ftplugin will expose an "Nwhich" function, which will start with the current path, and traverse up a directory until it finds a package.json and ./node_modules/.bin/<command arg>. It will fall back to which if it hits your root or home directory.
