Synopsis:	cn [node_path]
			cd [node_path]

Description:	changes the current node path to the argument.
				The current node path is used as the address for operation requests that
				don't contains the address part. If an operation request does include the address,
				the included address is considered relative to the current node path.
				The current node path may end on a node-type. In that case, to execute an operation
				specifying a node-name would be sufficient (e.g. logging:read-resource).

Arguments:

	node_path	- the new value for the current node path following the format
				[node-type [=node-name (,node-type[=node-name])*]].
				
The following navigation signs are supported in the node-path:
	/		- the root node (e.g. 'cd /' or 'cd /some=thing');
	..		- parent node (e.g. 'cd ..');
	.type	- node type of the current node (e.g. 'cd .type').
