 Group is just a regular profile room `m.social.feed` but with a

-This type is only an idea yet and should be defined more clearly.

-m.social.event

-
-This room type could be reserved for the event use case. i.e. for a
-single event, invite people and let each user say if he will be present.

-Idea:
-
-What should be defined for the event
-* name : [regular event] : room name 
-* main picture : [regular event] : room avatar
-* topic : [regular event] : room topic
-* event location
-* event time start
-* event time end
-* add a way to say if we will come (maybe use regular polls) 
-
-Regular events : the actual event is already defined in matrix,
-no need to reimplement.
