class IDGroup:
	"""
	The IDGroup Type
	================
	This type supports both iteration and the []
	operator to get child ID properties.
	
	You can also add new properties using the [] operator.
	For example::
	
		group['a float!'] = 0.0
		group['an int!'] = 0
		group['a string!'] = "hi!"
		group['an array!'] = [0, 0, 1.0, 0]
		
		group['a subgroup!] = {"float": 0.0, "an int": 1.0, "an array": [1, 2],
		  "another subgroup": {"a": 0.0, "str": "bleh"}}
	 
	Note that for arrays, the array type defaults to int unless a float is found
	while scanning the template list; if any floats are found, then the whole
	array is float.
	
	You can also delete properties with the del operator.  For example:
	
	del group['property']
	
	@ivar name: The name of the property
	@type name: string
