SGCondition* sgReadCondition	(	SGPropertyNode *	prop_root,
		const SGPropertyNode *	node
	)

Global function to make a condition out of properties.

The top-level is always an implicit 'and' group, whatever the node's name (it should usually be "condition").

Parameters:

node

The top-level condition node (usually named "condition").

Returns:

A pointer to a newly-allocated condition; it is the responsibility of the caller to delete the condition when it is no longer needed.
