        All arguments are optional:
        
        roomID - just a shortcut. Will return ONE room (not a list) or None.
        roomName - just a shortcut. Will return ONE room (not a list) or None.
        roomExample - example RoomBase object.
        reservationExample - example ReservationBase object. Represents reservation period.
        available - Bool, true if room must be available, false if must be booked, None if do not care
        freeText - str, room will be found if this string will be found anywhere in the object
            i.e. in equipment list, comments, responsible etc.
        minCapacity - Bool, defaults to False. If True, then rooms of capacity >= will be found.
            Otherwise capacity it looks for rooms with capacity within 20% range.
        allFast - Bool, defaults to False. If True, ALL active rooms will be returned

        customAtts - for rooms with custom attributes.

                     The customAtts attribute should be a list of dictionaries with the attributes "name", "allowEmpty", "filter".
                     "name" -> the name of the custom attribute
