  @brief
  A class that can be used for access to GData blogs. The new blogspot.com
  accounts ( August 2007 ) exclusively support GData API which is a standard
  based on Atom API. Compared to Blogger 1.0, which is based on Xml-Rpc and
  less secure, it adds new functionality like titles and comments.

  @code
  Blog* myblog = new GData("http://myblogspot.account.com");
  myblog->setProfileId( "2039484587348593945823" ); // can be fetched via fetchProfileId()
  myblog->setBlogId( "1" ); // can be caught by listBlogs()
  myblog->setUsername( "your_email@address.com" );
  myblog->setPassword( "yOuRFuNnYPasSword" );
