/**
 * Converts map to a simple wrapper, if applicable, by rewrapping
 * any map wrappers that implement <code>WrapperTemplateModel</code>.
 * <p>
 * This method is very permissive: anything that wraps a Map is accepted.
 * Other types of hashes are returned as-is.
 * <p>
 * If the specified ObjectWrapper is a BeansWrapper, this forces rewrapping as a SimpleMapModel.
 * If it isn't we assume caller specified an objectWrapper that will rewrap the map with
 * a simple model (we have no way of knowing).
 * <p>
 * WARN: Bypasses auto-escaping for complex maps; caller must decide how to handle
 * (e.g. the object wrapper used to rewrap the result).
 * Other types of maps are not altered.
 * 
 * @deprecated don't use
