A very rough commit of some code to create various graphs in Virtuoso
Trying out 4store. You need to install it yourself, but that's trivial. The code is in /bin, the data is in /4store. I haven't tried it at any kind of scale, but it was super-easy to set up and use.
Added a few more tasks to load various datasets
WIP.  Trying out Virtuoso stuff.
Refactored structured data code; Added class to test performance of Virtuoso (slow writes, fast reads) and 4store (fast writes, slow reads)
Merge branch 'master' into neo4j
Created test controller and views for data data; More refactoring of triplestore code
Merge branch 'master' into neo4j
Removed 4store and neo4j directories
Some basic changes for code design... no specs yet.
Okay, ironed out a few bugs, things appear to be working again. (Still need specs).
