cpp xstream 0.0.3

cpp xstream is a C++ flexible stream library.
cpp xstream is a collection of several streambuf and iostream classes that allow a programmer to compress and decompress data transparently with gzip or bzip2, to serialize composite types to xdr, to encode or decode with base64, and to tee output from one channel to several others. These streams can be stacked on each other.
Main features:
- Compressing and decompressing data using zlib and bzlib
- Encode and decode base64 data
- Serialize and deserialize structures to XDR
- Calculate digests of data
- Fork data written to a stream to several others
- Use file descriptors using a iostream interface (where available)
