void InitializeDataDirectory

This file is part of the CernVM File System. The functions in this file handle the management of the .data directory structure in the POSIX File System Traversal interface.

The .data directory structure contains (meta)content-adressable links to all inodes of the exported file system. This is used for deduplication. Method which initializes the .data directory with all subdirectories. Depending on kDirLevels and kDigitsPerDirLevel (defined in helpers.h) this process might be very slow.
