 Functionality of the toolbox 
 ---------------------------------------------------------------------------------------------
 Most of the Toolbox should work as it does in MATLAB although there will be some functions 
-that don't work correctly due to slight differences between MATLAB and Octave. 
-
-One area of difference is the lack of reference objects in Octave.  Link and SerialLink objects 
-inherit from the handle object in MATLAB which means that methods can change the value of the 
-object.  This is not possible in Octave yet.  So in MATLAB you can write
-
-obj.method(x)
-
-but in Octave you have to write
-
-obj = obj.method(x)
-
-where method(x) changes some property of the object.
