+	\class ResourcesContainer
+	\brief Represents a collection of resources.
+	
+	This class can be used to manage a collection of resources represented
+	by ResourceItem's. Usually it does never contain two resources with the
+	same type \em and ID, since AddResource() replaces an old item with the
+	new one, unless explicitly told not to do so. This should only be done
+	by ResourceFile, when type and ID of the items are not yet known.
+	Asside from the basic vector features like Add/RemoveResource()/
+	ResourceAt() and MakeEmpty() a bunch of IndexOf() methods are provided
+	and AssimilateResources() which incorporates all resources of another
+	container into this one (replacing old resources, if necessary), emptying
+	the other one.
+
+	The ResourceItem's in a container are deleted on destruction, unless
+	removed before via RemoveResource(). MakeEmpty() deletes the items as
+	well.
