Initial stab at wrapping relationships.

Fixed it, & included jazz-hands for debugging.

Trying out a wrapper & Neo4j::ActiveRelationship object.

Forgot to require new files.

Re-worked the wrapper code a bit to be more fail-safe, and added a
breakpoint for further debugging.

Removed breakpoint and symbolized keys in the data hash.

Not working, re-inserted debugger.

Fixing the wrapper method again.

Confirmed working, removed debug statement.

Working on cleaning up relationships a bit, allowing properties and
saving, as well as creating relationships with properties.

Updating requires.

Removing each_rel. Superfluous.

Removed jazz_hands which I was using for debugging.
