How to create a new confernce room

[remote-repo]

Thank you very much for making such a simple lib for doing xmpp which is already very hard for new developers to get started with.
However i have a query regarding creating a new group in xmpp server. Since docs does not have any function for doing that
it only has functions regarding muc chats.
I want to know how i can create and send stanzas via this client.
Pls provide the references how to create a stanza also.
Thanks
