    Class declarations for the REPL_EDIR_BASE and REPL_EDIR_x classes.

    REPL_EDIR_BASE is an abstract superclass that contains common methods
    and data members shared between the REPL_EDIR_x classes.

    The REPL_EDIR_x classes each represent a different info-level "view"
    of an exported directory in the Replicator's export path.

    The classes are structured as follows:

    	LOC_LM_OBJ
	|
	\---REPL_DIR_BASE
	    |
	    +---REPL_EDIR_BASE
	        |
 	        \---REPL_EDIR_0
	            |
	            \---REPL_EDIR_1
	                |
	                \---REPL_EDIR_2
