Ledger support

Because Chrome allows communication with the Ledger only from HTTPS loaded page (which chrome extension is not), there is a IFrame based transport implemented. This IFrame needs to be served on HTTPS. The source codes for the IFrame are at https://github.com/OntologyCommunityDevelopers/ledger-forwarder.git . To set the Iframe address make a call to

Ledger.setLedgerTransport(new Ledger.LedgerTransportIframe('https://drxwrxomfjdx5.cloudfront.net/forwarder.html', true));

To use your Ledger, you also needs Official Ontology Ledger App installed on your Ledger.
