Enabler for systrade app, the bitcoin trade web client.
This extension only works in combination with https://hinaser.github.io/systrade-web/app
This greatly improves update frequencies of board and execution history on bitFlyer FX market.
Also the extension automatically saves trading data to browser storage when tab/window is closed, so users can resume trading from the latest state.
In case you are interested in the actual code, please see my github repos.

If you would like to execute bitFlyer API from your web app on your browser, you might notice the response never come back.
It is because the API server doesn't send header like 'Access-Control-Allow-Origin: *'.
I expect bitFlyer assumes that all API users would execute API command from command line, not browser.
This add-on forcibly add 'Access-Control' headers to HTTP Response coming from 'api.bitflyer.jp' so that client send request/have response from the API server.
