Began work on ElasticSearchManager.
Contains basic get, add and delete methods, but more work needs to be
done.
Revert "Began work on ElasticSearchManager."

This reverts commit 43fe982fab2293f4a81e1759842a8fa1e2ad002f.
Added ElasticSearchManager.
Basic get, add and delete methods are there, but more stuff needs to be
implemented before they are usable. I based this directly off of the lab
implementation so I suggest using that as well moving forward.
Merge branch 'master' of https://github.com/g-chag/CMPUT301F14T01-Team1Project
