Copies hfs files from a 'mounted' disk.

hfscopy.py

# Mount iso: hmount path/to/file.iso
# Do: hls -aqRF1 > files.txt
# and run: python hfscopy.py
# explanation
# -a Show all files
# -q print '?' instead of escaped chars
# -R descend into all directories
# -F enable file type flag, dir: executable:*
# -1 output 1 item per line

# Ideas:
# copy 'real' filename over when it has a '?'.
# do a double pass, first create the directories
# convert it into objects, an object per file/directory?
