##
# Base class from where the specialized parsers inherit from.
#
# On initialization a main parser is expected, so the specialized
# parsers can request the parsed document to the main parser, and
# then perform the searches on it.
#
# The main parser also serves as a message hub between the specialized
# parsers. For example, the ImagesParser needs to know the base_url
# in order to absolutify image URLs, so it delegates it to the main parser
# which, in turn, delegates it to the LinksParser.
#
