Details - Making the type of the second matrix for +=, -= and axpy a template parameter (and using iterators instead of [] internally) allows to add other matrices like e.g. ScaledIdentityMatrix without further code and with optimal efficiency.

Although this changes the interface it does neighter change the use with FieldMatrix nor the performance.

However it might change the behaviour if you used a+=b where b has a cast to FieldMatrix.
