+ base.js fixtures now include percentage data
+ slickgrid tests updated to hide p field in fixtures
+ added test scenario for percentage data in tests for flot view
* Now have Dataset setup and manage "memory store"
* New fetch API as per issue #162 spec
* dataproxy utilizes useMemoryStore attribute and just implements fetch
* Switch gdocs to use Memory.Store properly via new useMemoryStore + fetch methodology
* Memory backend: query function now follows promise API, remove fetch,upsert,delete and add save function to Store object
* Also refactor to remove _source in QueryResult "hits" attribute on all backends but ElasticSearch - cf #159 (note this means ES currently broken)
* TODO / problems: have hard-coded ticks to be yyyy-MMM but that may not work well for all time series (may need to guess this from the resolution of the data or allow user to configure)
