-To run "gopherjs test -v" you must "npm install pouchdb" (which actually runs on top of levelDB). 
-Also need to "npm install pouchdb-find" for queries.
-When running "gopherjs test" from the ouch directory, a pouchdb.test directory will be created (in .gitignore).
-
-To run "go test" a publiclly accessable CouchDB must be at "http://127.0.0.1:5984/ouchtest" with an administrator account testusername:testpassword (basic auth only, as this also works from the browser).

-* I suggest that all the Database interface methods have context as the first parameter, and that context is removed from all the "child" methods (like Query.One).
-* Reply from dennwc37: This might not work well for DocIterator - it might be passed around and should use the context of the last caller, not the first one. I would say it make sense we can add contexts to Insert, FindByKey and EnsureIndexes and leave other builders as-is, since they already pass context in Do, One, Next, etc.

-## TODO
-
-* Report GopherJS bug type conversion in graph/graphtest/graphtest.go:IteratedQuads()
-* add Query.Limit() test (and is 1M large enough as the default)
-* work out how to delete test db remotely from JS using PouchDB as front-end to CouchDB, so as to test remote from JS
-* work out how to implement and test PouchDB/CouchDB replication
-* review error handling in from/to Ouch Value/Doc?
-* test on live app with instrumentation, to find further optimisation possibilities
-* investigate using []interface{} for key values in the Strings type - @dennwc said: "This was actually the reason why I dropped nosql.Key for Value interface - it's now the only array type that is supported. So if kivik can store json array, this can be an indication that Strings is stored there."
