Four spaces not two for json
Return schema by data_type

- just say 'schema for <type/data-set>' for now in the description
Reference property '_timestamp' as '_timestamp' not 'timestamp'
Show full diffs in nose

- culled from http://stackoverflow.com/questions/14493670/how-to-set-self-maxdiff-in-nose-to-get-full-diff-output
- Was really useful for expected schema vs returned
Modify the default schema in data-set view tests

- Now passes the name of the data-set to the retreiver function, so we get the name in the description
- The name is overwritten several times so the function is called in an assertion loop, feels weird.
- Probably not sustainable to do this. TODO: bounce to separate test class, but only ask for certain parts of the fixture to be matched here?
Add in a monitoring schema to the view test case

- pretty chonky to just shove the schema into the class as a dict
- feels dumb to switch in a loop, but it does test accurately
