5d887e468e I've made SparseRealVector and SparseRealMatrix to be empty marker interfaces. 
I've left OpenMapRealVector.getSparcity, since I'd like to use it for benchmarking, and it doesn't hurt anyone else now.

1ed2b9afc5 Changing DenseRealMatrix to return a specific type, instead of interface type. 
I beleive the consensus is to leave RealMatrixImpl and RealVectorImpl alone for now (since they were in 1.2), so that's what I'm doing.

5ce6c81490 Sparse Matrix/Vector refactoring with mostly return types changed. 
Thought that getSparcity was meaninful for SparseRealVector, and added a marker for SparseRealMatrix shape.  Feel free to -1 either ;).

I found an error in the unit tests, so will commit the changes there shortly, after a review.

4d3b3886f9 simplified DifferentiableMultivariateVectorialFunction 
the gradient and partial derivaritves can be retrieved from the jacobian
and adding them at the interface level was cumbersome for implementing
optimization problems.
Now users need to provide only the jacobian method
