   attempting to encode them within HttpClient.

 * 'Expect: 100-continue' logic factored out into an abstract 
   ExpectContinueMethod class

 * 'Expect: 100-Continue' handshake disabled per default, as it may not work 
   properly with older HTTP/1.0 servers or proxies.

 * Reengineered authentication code.  This includes a fix for 
   HttpClient continually attempting to authenticate to digest realms and 
   provides for better future extensibility.

 * Authenticator class deprecated

 * Improved user documentation and example code.

 * Added ability to differentiate between different hosts using the 
   same realm names.

   required for future compatibility)

 * Renamed HttpMethod.followRedirects to getFollowRedirects,
   for consistency (and made the corresponding change to
   HttpMethodBase)
