Modified: src/share/org/apache/struts/tiles TilesUtil.java
Added: src/share/org/apache/struts/tiles
TilesUtilStrutsModulesImpl.java
TilesUtilStrutsImpl.java TilesUtilImpl.java
Log:
Change the TilesUtil implementations hierarchie:
TilesUtil is the main entry
TilesUtilImpl is the root and default implementation
TilesUtilStrutsImpl is the implementation for struts
TilesUtilStrutsModuleImpl is the implementation for struts with multi module.
Normal user doesn't have to take care about the implementation to use. It is
selected by the TilesPlugin
