I'll do some testing on this, but I'm guessing PRO: (1) smaller index size
and (2) smaller messages over the wire. CON: Need to take care when
println'ing the query.

> MongoDB will reject statements they contain very long linestrings.
> Basically, the mongodb index key is limited to 1024 chars, so the insert will
> fail if the literal is longer.
> [Here is some example
> code|https://github.com/amihalik/rya-mongo-debugging/blob/master/src/main/java/com/github/amihalik/rya/mongo/debugging/linestring/LoadLineString.java].
> I think the inserts will work if you use 10 points, but fail if you use
> linestrings with 100 points.
