added new namespace Rapid + Blank class
added new namespace Rapid + Blank class

Rapid namespace stands for Rapid Prototyping or Rapid
Development. Its still a little bit open but the purpose
of the first class Blank is that you map a SPARQL result,
containing properties and objects, to an PHP instance to
enable easy access.

Image the following result array:

array (size=2)
'p' =>
    object(Saft\Rdf\NamedNodeImpl) 'uri' => string
'http://www.w3.org/1999/02/22-rdf-syntax-ns#type'
'o' =>
    object(Saft\Rdf\NamedNodeImpl) 'uri' => string
'http://www.w3.org/2002/07/owl#Class'

mapped to an instance enables the following usage:

$blank['http://www.w3.org/1999/02/22-rdf-syntax-ns#type'] =
'http://www.w3.org/2002/07/owl#Class';

or shorter

$blank['rdf:type'] = 'http://www.w3.org/2002/07/owl#Class';

Easy, hm?
