CreateGroup.md

Creating the group.

Implementation note
If the host is an iPhone, then the presence of all in the contact list is mandatory.
The group will be added to the queue for sending and created sooner or later, even if the phone is disconnected from the Internet or authorization is not passed.
Update from October 2, 2018: In the response, the chatId parameter will be filled in if it was possible to create a group on your phone within 20 seconds.
This method is available in both synchronous and asynchronous implementations.
