Collecting Autocomplete Input

• after creating an autocomplete - your bot will begin to receive interactions that are the result of inputs coming from the commands for which you enabled autocomplete - and you listen for these using the discord_core_api::event_manager::onAutoCompleteEntry event.
• create a function which returns void and takes an argument of type discord_core_api::on_auto_complete_entry_data, and use it to filter for and provide responses to various inputs.
• the user's current text inputs will come in on the discord_core_api::input_event_data's discord_core_api::interaction_data::data's, discord_core_api::application_command_interaction_data_option array of options.
• use these inputs in order to construct a discord_core_api::respond_to_input_event_data response, using the discord_core_api::respond_to_input_event_data::setAutoCompleteChoice function - and send it off to the discord servers in order to provide the user with suggestions for autocomplete.
• upon receiving a collection of choices, the user may choose one and respond, at which point you will receive it in the form of an incoming discord_core_api::interaction_data with the respective choices set.
