Fixing the code in ContextNodesInclusionFactory. getQueryFromModel() is commented out because there is nothing specified in search.n3 to be read into the model during the startup.

Eventually, all the contextnode queries willl be extracted out into search.n3

* bk392 : The original idea behind writing up this method was to check
* if I can read the queries from search.n3, write them to the displayOntModel(during startup) and
* read them in this class.
*
* Eventually, its going to be like that. All these hardcoded queries
* will go into search.n3 and will be written into the display model.
* ContextNodesInclusionFactors gets the queries out from the display Model
* and fires them, gets the values, concatenates them and passes them back to
* IndividualToSolrDoc.
