Let's say if we have this condition:

	c1 = Has('A', '$x', '$x')

and the following WMEs:

	WME('A', '0', '2'),
	WME('A', '1', '1').

The condition should be satisfied only by the second WME, but not the first.
However, Naive-Rete seems to activate both conditions.

Hi: what would be the license for this repo?
Thanks!

In file common.py, line 217:

jr.wme.negative_join_results.remove(jr)

there is an extra s in the function name. It should be negative_join_result.

In file ncc_node.py, line 65:

Token.delete_token_and_descendents(token)

should actually be Token.delete_descendents_of_token(token).

This function is explained in [Doorenbos 1995] section 2.8 (p.49). The pseudo-code is in p.158 of Appendix A.

Just add this function in Python, under class Token, in common.py:

@classmethod
def delete_descendents_of_token(cls, t):
    """
    :type t: Token
    """
    while t.children != []:
        cls.delete_token_and_descendents(t.children[0])

When the bug is not fixed, we get some errors when an NCC Partner node tries to delete tokens and complains that the tokens are not in the list.
