Constructs a new layered dictionary :
dicts : a list of dictionaries to layer. dicts[0] has highest precedence and dicts[-1] lowest. after construction this list can be accessed as LayeredDict.layers, and may be modified in place to change the layering.
dictClasses : a set of classes to consider as dictionary types. this comes into play when layeredDict["key"] yields an object of that type. in this case the object is not returned alone, but instead a new LayeredDict of that object and any others with the same key is returned - this allows the layering to continue in dictionaries held within the topmost dictionary.
