This patch will sit above Geralds one to sort out last minute things
including:

- upgrade compatibility
-- Will need to compare current elasticsearch version with compatible
version and alert about problems
-- Will allow one to set the shards/replicas as part of config
-- alert the cluster health (non green) status and unallocated replica
shards

- Allow empty search query to return all related results
- Allow collections to record / search on collection tags
- Index group access correctly
- Get correct results to display for each tab rather than all results
bunched together
- Allow highlight on description field

- Add a basic behat test
- removed the built in docs/ and tests/ dirs as well as the phpunit
test files
