		struct Node *	to,
		struct Message *	out_msg
	)

Computes the product of messages incoming to a node.

Computes the product of messages incoming to a node, with the exception of the message coming from the node to which the computed message will be going, In other words, computes \(\prod_{k \in \partial i - j} \mu_{ki}(x_i)\).

Parameters

from	the node from which the message is coming
to	the node to which the message is going
out_msg	the message in which to store the result
