# == Strings and IO Objects as Input
#
# Loofah.document and Loofah.fragment accept any IO object in addition
# to accepting a string. That IO object could be a file, or a socket,
# or a StringIO, or anything that responds to +read+ and
# +close+. Which makes it particularly easy to sanitize mass
# quantities of docs.
