* Add short documentation for Array class * Put all classes explicitly in Core module (where applicable) * Section on Modules in Quick Reference Guide * Put Page 7 after Page 6 in Contents :)
- all what's not in unsupported/ is considered stable API (except internal stuff e.g. expression templates).
- mv Array/* into Core/ - merge Functors.h files, and move Norms.h into Dot.h
