Initializer. Takes optional type, content, and name. The type, if given, must be a symbol type (>= 256). If the type is None this matches *any* single node (leaf or not), except if content is not None, in which it only matches non-leaf nodes that also match the content pattern. The content, if not None, must be a sequence of Patterns that must match the node's children exactly. If the content is given, the type must not be None. If a name is given, the matching node is stored in the results dict under that key.
Match the pattern's content to the node's children. This assumes the node type matches and self.content is not None. Returns True if it matches, False if not. If results is not None, it must be a dict which will be updated with the nodes matching named subpatterns. When returning False, the results dict may still be updated.
