Created April 18, 2018 23:47
A no-op storage driver for gun, in case gun has no other storage; at least one ack from a storage device is required for the engine to work....
Gun.on('opt', function(ctx){
const ACK_ = '@';
const SEQ_ = '#';
var gun = ctx.gun;
this.to.next(ctx);
ctx.on('put', function(at) {
this.to.next(at);
ctx.on('in', {[ACK_]: at[SEQ_], gun:gun, ok: 1});
