A Pipable Filter can appear as a component of a pipline.
     Certian overloads of operator| must be defined to make a Filter Pipable; this is achieved by invoking the macro BOOST_IOSTREAMS_PIPABLE.
| P | - | A type which is a model of Pipable | 
| C | - | A type which is a model of Filter or Device and which is CopyConstructible[1] | 
| p | - | Object of type P | 
| c | - | Object of type C | 
| Expression | Expression Type | Semantics | 
|---|---|---|
|  | implementation-defined | Returns a pipeline corresponding to the sequence f,c | 
None.
[1]This requirement prevents streams and stream buffers from appearing in pipelines without the use of reference wrappers. This restriction may be removed in a future version of the Iostreams library.
