Split GenericInflater into SimpleInflater, which wraps the XML parsing into finding the tag name and an AttributeSet. The subclass is responsible for creating the corresponding object for the given tag name and AttributeSet. ReflectionInflater is a subclass of SimpleInflater which will treat the tag name as a class, and create the object via reflection using the 2-argument constructor TagName(Context, AttributeSet).
