Abstract engine interface for view layer, provides a means to make view method calls standardised regardless of rendering engine. If a method is not implemented in the template engine, then it should still be implemented but just return the engine instead e.g. for those template layers that do not have a config directory; simply return $this.
All engines should inherit from this class an must implement all methods whether the engine actually uses them or not. The extension class must be named:
mvcViewEngineTYPE
Where TYPE is the short name for the engine e.g. Smarty has an engine class named mvcViewEngineSmarty, PHPTal could be mvcViewEnginePhptal etc.
