aoqi@0	33	* Interface for determining locally available program elements, such as
aoqi@0	34	* local variables and imports.
aoqi@0	35	* Upon creation, a Scope is associated with a given program position;
aoqi@0	36	* for example, a {@linkplain Tree tree node}. This position may be used to
aoqi@0	37	* infer an enclosing method and/or class.
aoqi@0	38	*
aoqi@0	39	* <p>A Scope does not itself contain the details of the elements corresponding
aoqi@0	40	* to the parameters, methods and fields of the methods and classes containing
aoqi@0	41	* its position. However, these elements can be determined from the enclosing
aoqi@0	42	* elements.
aoqi@0	43	*
aoqi@0	44	* <p>Scopes may be contained in an enclosing scope. The outermost scope contains
aoqi@0	45	* those elements available via "star import" declarations; the scope within that
aoqi@0	46	* contains the top level elements of the compilation unit, including any named
aoqi@0	47	* imports.
