dff725b2e8 Added a RealTransformer interface on top of cosine, sine and Hadamard transforms. 
The Fourier transform cannot implement this interface since it produces complex results.

f8cc8e9d37 Added method to walk matrix entries with or without changing them in the 
visitor design pattern sense. Two different orders can be used, row by row
of following internal storage. Internal order should be preferred when no
specific order is needed, because it will be more cache efficient.

25a6b32fe1 prepared interface for general eigendecomposition 
we currently support only symmetric matrices and real eigenvalues
Jira issue MATH-235 asks for asymmetric matrices support, which needs
an API adaptation.
Preparing the interface yet avoids introducing incompatibility later.
The current status is explained in javadoc and matrix symmetry is checked
at runtime with an InvalidMatrixException triggered if asymmetry is detected.
