Demo: http://open-explorer.io/bitshares-account-exporter/index.php
The repo host an account exporter for bitshares, highly demanded by the community.
All bitshares 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/oxarbitrage/bitshares-es-wrapper) connected to a bitshares node with elasticsearch plugin to pull account operation history and present it in CSV format.
