hey, Can have a function ( remove single node)?

[GarfieldLinux]

Hey :
Nice work,nice trie .
I just found method trie_free() , but it free all the data . Is there a function to remove single node (self child ), I can't have enough mem all the time .
I used the trie for storing url rules , sometimes I need to remove some unuseful urls .
by the way , your trie insert urls so fast .
thanks your work .

Right now there's no way to free trie nodes. If you set the data pointer to NULL the nodes are left behind, though they will _not_ be visited (making them effectively deleted). These empty branches are left flapping in the breeze so to speak, though the nodes that make them up would be reused if that particular prefix is inserted again later. There isn't a technical reason for this. I just didn't add this functionality since I haven't needed it.
