print a binary tree of integers in level order. Level-order printing means printing each row of the tree from left to right, from root row to the deepest row. After each row, print a newline.

	import Queue

	class tr:
	def __init__(self,val=None,children=None):
	self.val=val
	self.children=children or []

	def emit_level_order(tree):
	cur_level = 0
	q = Queue.Queue()
