Update 253-Meeting-Rooms-ii.py

It appears that Leetcode updated this question where they removed the custom definitions for this problem. Before the definition was: 
"""
class Interval (Object):
     def __init__ (self, start, end):
             self.start = start
             self.end = end

 def minMeetingRooms(self, intervals):
        start = sorted([i.start for i in intervals])
        end = sorted([i.end for i in intervals])
"""
Without the custom definition the current solution needs to be updated to use indexes as follows:
"""
start = sorted([i[0] for i in intervals])
end = sorted([i[1] for i in intervals])
"""
