    Helper function to parse the HTTP ACCEPT header

    str : str headers to parse

    parseAcceptHeader = (str)->
  index = 0

  str.split(/,\s+/).map((accept_str)->
    parts = accept_str.split(/;\s+/)
    [type, subtype] = parts.shift().split('/')
    params = {
      q: 1.0
    }

    RFC is unclear about level param so don’t treat that specially http://stackoverflow.com/questions/13890996/http-accept-level http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

        for param in parts
      [name, val] = param.split('=')
      if (name is 'q')
        val = parseFloat(val)
      params[name] = val
    
    {
      index   : index++
      type    : type
      subtype : subtype
      params  : params
    }      
  ).sort((a, b)->
    if (a.params.q is b.params.q) 
      a.index - b.index
    else
      b.params.q - a.params.q
  )
