> Existing HTTP source handlers recieve events via a HTTPServletRequest.  This works, but because the handler doesn't have access to the HTTPServletResponse, there is no ability to return a response.  This makes it unsuitable for some sort of protocol that relies on bidirectional communication.
> My solution: In addition to the existing HTTPSource interface, I've added a BidirectionalHTTPSource interface that is provided the servlet response as a parameter.  I've made some changes in the HTTP source allow for both types to co-exist, and my changes shouldn't affect anyone who is already using the existing interface.
> Also includes minor documentation updates to reflect this.
