15:40 CoCoALib Bug #631 (Closed): Ambiguous: rank for matrix (in ex-matrix1.C)

- Added maintainer doc, test (seems its was needed), and example (a bit difficult).
-
- Implemented, and added some doc.
Still need to do: maintainer doc, test, example.
-
- In an example I needed a table like the Sieve of Eratosthenes. So I've implemented it, and added it to CoCoALib.

- Compilation of GUI for windows by Jan Limbeck (thanks!)
tested, worked, published!
all done now

Would it be useful in CoCoALib? maybe just a random subset of 1..n? -
