UnifiedI/O allows to access files, arrays, streams (even over HTTP) using
one common interface, and gives a clear difference between read only and
read/write access.

Features:

- High performance.
- Transparent buffering.
- Random access.
- Access everything using one common interface.
- Read/write direct from/into primitive arrays
- Choose byte order.
- Change byte order at any time.
- Define start offset and length.
- Optimized reading over http (only requesting the required data range of
bytes - uses byteserving feature of http 1.1).
- Easy extensible design

Unified I/O contains also many utilities:
- BitInputStream and BitOutputStream.
- PackBits, RLE4 and RLE8 decoder.
- base64 codec implementation.
- and many others.

Unified I/O is an open source project and licensed under BSD.

Changes:
- RLEInputStream, RLE4InputStream, and RLE8InputStream were added.
- ByteArrayOutputStreamExt was added to help implement a simple buffer.
- JUnit tests added for the RLE4 and RLE8 decoder.
