True if Trie exists with Property. Intended for debugging and statistical purposes. Retrieving some of these properties visit all nodes of the trie. Defined properties are

node_count(-Count): Number of nodes in the trie.
size(-Bytes): Required storage space of the trie.
hashed(-Count): Number of nodes that use a hashed index to its children.
