A Markable Stream functions as an ordinary writer with the added ability to mark a stream at an arbitrary location that can be returned to after subsequent reads. There are two variants in this package: 1) Markable Stream; and 2) Buffered Markable Stream.
Usage is the same as with any other std::io::Read trait, with the exception of two additional functions: mark() and reset(), which mark the location of the stream to return to at a later point and reset the stream back to that position respectively.
