2d4c07b56d Make db name-literal agnostic 
Move the persistence characteristic of the store into the graph registry
and provide an API hook to get that information.

Add error return for init on a non-persistent store.

Updates #35.

401c58426f 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.

0e0e382d2b 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.

1768e593a8 Move iterators into separate package 
Also reduce API exposure and use standard library more - and fix bugs I
previously introduces in mongo.

0a03cec497 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.

e0df752618 Reorganize to go get will work 
This makes almost no changes to source, but touches every almost file.

Also fixes error in gremlin test code.
