Public Class Methods
Find the class to use given the name and namespace of a stanza
@param [#to_s] name the name to lookup @param [String, nil] xmlns the namespace the node belongs to @return [Class, nil] the class appropriate for the name/ns combination

Import an XML::Node to the appropriate class
Looks up the class the node should be then creates it based on the elements of the XML::Node @param [XML::Node] node the node to import @return the appropriate object based on the node name and namespace

Register a new stanza class to a name and/or namespace
This registers a namespace that is used when looking up the class name of the object to instantiate when a new stanza is received
@param [#to_s] name the name of the node @param [String, nil] ns the namespace the node belongs to
