Prevent duplicate parses of same data, in the same recursive descent
When parsing if there is a loop in the data being parsed, the
recursions will just keep cycling until it exhausts memory and
crashes. This CL introduces a parsed set, which a reference to is
passed down the descent. If the data being parsed at a specific stage
of the descent is already in the parsed set, then the parse returns at
that point.
