Modular storage layout > HBase core module

[GoogleCodeExporter]

After issue 57 [1] (modular storage layout) has been addressed, add a HBase 
core module implementation.

For this, have look at existing HBase implementations:
* https://github.com/ahaque/hive-hbase-rdf
* https://github.com/mhausenblas/mrlin/wiki/RDF-in-HBase

However, I think we should aim for implementing the indexes all triple patterns 
[2] - as done for our Cassandra implementation. Plus, the indexes for the range 
queries would be a nice feature. 

For further details on these indexes, see the original paper [3].

Kind regards
Andreas
