function to query the exiobase data from rdf data base and turn into numpy SUT

This function requires the EIXOBASE data to be in the rdf database. 

It should query the data the output should be a two numpy arrays with the SUT values and the meta data (process names, units etc) in separate arrays/to be defined data structures. this meta data will need to be used to later turn the A-matrix (IO-table) back into rdf format to be pushed back to the database.
