replace some transformations by SPARQL-UPDATE transformations

[janpolowinski]

• check whether performance/readability increases
• use experiments created when experimenting with SPIN
• some examples noted here (not all correct evtl.): http://answers.semanticweb.com/questions/11704/which-graph-transformation-rules-are-possible-with-sparqlupdate-and-which-are-not
• maybe aim at composability of graph transformations by integrating SPIN (API)

[janpolowinski]

one example could be to create a labeling relation for all literals:

UPDATE ... ?go :labeled_with ?newLabelRelation . ?newLabelRelation :labeling_label ?newLabel . WHERE ....
