The repo host an account exporter for Graphene, highly demanded by the community.
All graphene related stuff is at index.php, the rest is just dependencies to make the form looks a bit prettier.
The exporter will use an ElasticSearch Wrapper instance(https://github.com/graphene-blockchain/graphene-explorer-api) connected to a bitshares node with elasticsearch plugin to pull account operation history and present it in CSV format.
