Create quads hierarchy
...
* Move nquads into quad.
* Create cquads simplified parser in quad.
* Move Triple (renamed Quad) to quad.
Also made sure mongo actually implements BulkLoader.

Use error returns and interface type for parsing
...
Fixes issue #72
This change simplifies interactions with parsing N-Quads and makes
reading datasets more robust. Changes made while here also improve
performance:
benchmark old ns/op new ns/op delta
BenchmarkParser 1058 667 -36.96%
We still use string concatenation which I'm not wildly happy about, but
I think this can be left for a later change.
Initial changes towards idiomatic error handling have been made. More
significant changes are needed, but these have subtle design implication
and need to be thought about more.
30kmoviesdata.nt.gz has been altered to properly escape double quotes.
This was done mechanically and with manual curation to pick up
straglers.

Also reduce API exposure and use standard library more - and fix bugs I
previously introduces in mongo.

Replace string type with graph.Direction
...
This conversion is not complete as there are still uses of string
directions via the Direction.String method in leveldb.
