CHANGE LOG:
[04.12.2012]
+ adding various fixes (thanks to: Kristofer Sandlund)
+ adding read support for objects, java objects, other types
+ performance enhancements

[05.10.2007]
+ Sparse matrix bugfixes by Jonas Pettersson (LU/EAB)
+ MatFileReader performance enhancements by Eugene Rudoy
+ new MatFileReader methods added

[02.03.2007]
+ Regression bug fixed: Double arrays created natively in Matlab are read 
  incorrectly (reversed byte ordering)

[22.02.2007]
+ Added support:UInt8 array 
+ MAJOR reading performance enhancement - reading is as fast as in Matlab now
+ Removed Log4j references

TODO:
- Other array types (serialized objects (OPAQUE) is done partially)
- Writer performance enhancement
- Documentation and examples
- Organize JUnit tests
- Refactor exceptions
- Make structures and cell arrays more user friendly

NOTE:
Numerical arrays (MLDouble, MLUint8) are now backed by direct ByteBuffers. For 
really BIG arrays the maximum heap size for direct buffers may be modified by 
-XX:MaxDirectMemorySize=<size>


[some.time.2006]
Currently supproted data types are:
+ Double array
+ Char array
+ Structure
+ Cell array
+ Sparase array
