SUMMARY
-------

* Bugs: All known 4 bugs have been fixed.
* Completely revised and extended interpolation toolkit.
* New complex matrix and vector type (Complex Linear Algebra will follow in the next iteration).
* Slightly enhanced real matrix and vector types .
* QR decompositions are now unique (positive real R diagonal).
* Complex type now has a public constructor, more intuitive.
* New Digamma (Psi) special function.
* Various other small changes.
