invert The class template inverse is an adapter which transforms
      an InputFilter into an OutputFilter
      or vice versa. The function template invert is an object generator which when passed a Filter returns a
      instance of an appropriate specialization of inverse.
    
Given an InputFilter f,
      the inverse of f is Multi-Character
      OutputFilter whose member
      function write is implemented as follows. Given a Sink
      snk and a character type buffer s of length n,
      we
    
s and compose
        it with f to form a Source, then snk until the buffer s is
        exhausted.
      Similarly, given an OutputFilter
      f, the inverse of f is Multi-Character
      InputFilter whose member
      function read is implemented as follows. Given a Source
      src and a character type buffer s of length n,
      we
    
s and compose
        it with f to form a Sink, then src
        and write them to the composite Sink until the buffer s is
        full.
       The mode of a specialization of inverse
      is equal to output if the mode
      of the underlying filter refines input, and to input
      otherwise.
