istreamb, ostreamb, and iostreamb are streams just like istream,
ostream, and iostream except for two features. First, they
automatically insert and extract delimiters around datums where
necessary so you never have to separate datums by whitespace yourself.
Second, they can insert and extract integers as either unformatted
(binary) bytes or formatted characters so you can eliminate the time
needed to convert integers to strings and back. Both of these
features make these classes easier to use than the base stream classes
for inter-process communication (IPC).
