/**
* class to encapsulate the 'stuff' for internal operation of velocity.
* We use the context as a thread-safe storage : we take advantage of the
* fact that it's a visitor of sorts to all nodes (that matter) of the
* AST during init() and render().
* Currently, it carries the template name for namespace
* support, as well as node-local context data introspection caching.
*
* Note that this is not a public class. It is for package access only to
* keep application code from accessing the internals, as AbstractContext
* is derived from this.
