working on elasticsearch.
Elasticsearch able to retrieve id.
Added a new attribute of comment which is a comment property that will point to the topic level parent of a child comment and will be used in updating elasticsearch correctly.
Changed some comment code.
Finshed implementing saving replies using an elasticsearch id and updating by propagating up towards a comment that is topic level and updating it.
Fixing adding replies to elasticsearch.
Fixed the implementation to update elastic search with the comment replies. Now need to fix elastic search query.
Added back some code that was deleted on last commit.
Fixed the replying so no crashes in the app but elastic search saving reply still needs fixing.
