# This class both copies necessary files to
# a temporary directory, generates a temporary TOC page,
# and opens the generated html document in a web browser,
# by default "index.html" (unchangeable).
# <br/>
# Since the files are both static and dynamic (some are always the same,
# while other change according to user choices)
# I divide this tasks to two: all necessary
# static files, which should not regularily update are copied upon
# instanciation.
# The TOC is generated in refresh(...);
