/**
* Class to handle m.room.power_levels event
*
* This event specifies the minimum level a user must have in order to
* perform a certain action. It also specifies the levels of each user
* in the room. If a user_id is in the users list, then that user_id
* has the associated power level. Otherwise they have the default
* level users_default. If users_default is not supplied, it is
* assumed to be 0. The level required to send a certain event is
* governed by events, state_default and events_default. If an event
* type is specified in events, then the user must have at least the
* level specified in order to send that event. If the event type is
* not supplied, it defaults to events_default for Message Events and
* state_default for State Events.
