    Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.

    This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.

    Usage

    var headers = {}
      , c = caseless(headers)
      ;
    c.set('a-Header', 'asdf')
    c.get('a-header') === 'asdf'

    has(key)

    Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.

    c.has('a-header') === 'a-Header'

    set(key, value[, clobber=true])

    Set is fairly straight forward except that if the header exists and clobber is disabled it will add ','+value to the existing header.

    c.set('a-Header', 'fdas')
    c.set('a-HEADER', 'more', false)
    c.get('a-header') === 'fdsa,more'

    swap(key)

    Swaps the casing of a header with the new one that is passed in.

    var headers = {}
      , c = caseless(headers)
      ;
    c.set('a-Header', 'fdas')
    c.swap('a-HEADER')
    c.has('a-header') === 'a-HEADER'
    headers === {'a-HEADER': 'fdas'}
