vignette was failing around line 140.
I've commented out the failing bit for now to get the vignette to work.

Some objects (location being the obvious one) are likely to be repeated multiple times within a dataset. To prevent this duplication we should perhaps permit a cache key on the same level as metadata and records that will contain an object with keys (md5, sha?) that can be referred to later in the file. Eg

"cache": { "e54789a3": {a GeoJSON boject},
                "680f038d": "A base64 encoded file"}
}

Records in the cache could then be referred to in other elements of the file with a cache object

 "location":{"ref$": "e54789a3" }

At the moment dates must be defined as a timestamp. We should, in later versions, permit just date to avoid false precision.

Travis currently complains about a missing configuration file. Need to check that the relevant files were added - use_travis() in devtools.

Basic example where the unit of observation is a case.
