* Adds Overload to AddIndexOption Simplify usage. We don't need to create/add the underlying explicitly, see AddIndexOption(string, Resolution, string, bool) overload. * Addresses Peer-Review - Default market is `null` instead of `Market.USA` allowing for `BrokerageModel` setup. - `AddIndexOption` and `AddIndexOptionContract` methods now return `indexOption` objects. * Fixes Logic Bug
