create more than one <?predicate?> per column

[efotopoulou]

In the majority of times when a csv file is RDFizes the end user desires to be able to interlink the RDF result file with many other RDF dump files of sparqlendpoint datasets.

It would be really important to be able to create more than one per column.

for example if a column contains year , be able to create dbpedia:year AND lgdo:year. that way the result RDF file is more inter linkable.
