Olm
===

Note: before using any of the olm functions, you must call `Olm.init()`, and
wait for the promise to resolve, otherwise you will get errors like:
`Uncaught TypeError: Olm.Account is not a constructor`

Example:

    var alice = new Olm.Account();
    var bob = new Olm.Account();
    alice.create();
    bob.create();
    bob.generate_one_time_keys(1);

    var bobs_id_keys = JSON.parse(bob.identity_keys());
    var bobs_id_key = bobs_id_keys.curve25519;
    var bobs_ot_keys = JSON.parse(bob.one_time_keys());
    for (key in bobs_ot_keys.curve25519) {
        var bobs_ot_key = bobs_ot_keys.curve25519[key];
    }

    alice_session = new Olm.Session();
    alice_session.create_outbound(alice, bobs_id_key, bobs_ot_key);
    alice_message = a_session.encrypt("Hello");

    bob_session.create_inbound(bob, bob_message);
    var plaintext = bob_session.decrypt(message_1.type, bob_message);
    bob.remove_one_time_keys(bob_session);


Group chat:

    var outbound_session = new Olm.OutboundGroupSession();
    outbound_session.create();

    // exchange these over a secure channel
    var session_id = group_session.session_id();
    var session_key = group_session.session_key();
    var message_index = group_session.message_index();

    var inbound_session = new Olm.InboundGroupSession();
    inbound_session.create(message_index, session_key);

    var ciphertext = outbound_session.encrypt("Hello");
    var plaintext = inbound_session.decrypt(ciphertext);
