/* ######################################################################

   File Listing - Manages a Cache of File -> Package names.

   This is identical to the Package cache, except that the generator 
   (which is much simpler) is integrated directly into the main class, 
   and it has been designed to handle live updates.
   
   The storage content of the class is maintained in a memory map and is
   written directly to the file system. Performance is traded against 
   space to give something that performs well and remains small.
   The average per file usage is 32 bytes which yeilds about a meg every
   36k files. Directory paths are collected into a binary tree and stored
   only once, this offsets the cost of the hash nodes enough to keep 
   memory usage slightly less than the sum of the filenames.
 
   The file names are stored into a fixed size chained hash table that is
   linked to the package name and to the directory component. 

   Each file node has a set of associated flags that indicate the current
   state of the file.
