4b6b25d558 Removed Java6 @Override annotations. 
@Override is needed in Java6 when implementing an interface, but is
allowed only when overriding a previous implementation in Java5. Apache
Commons Math currently targets Java5, so these annotations were
spurious.

c528afa780 Added SparseGradient to deal efficiently with numerous variables. 
This new class is devoted to differentiation computation when the number
of variables is very large but most computations depend only on a few of
subset of the variables.

Thanks to Ajo Fod for the contribution.
