Charles: missing vector iterators

[porton@ex-code.com (Victor Porton)]

Why in Charles.Vectors iterators are missing even despite it is 
modelled after STL?

Iterators are good for many things, including reliability:

In enclosed loops:

for i in ... loop
  for j in ... loop
    ...
  end loop;
end loop;

personally I often mess I and J. Probability to mess iterators is 
lesser than to mess natural number indexes because iterators are more 
type-safe.

Please add these.

BTW, may be put Chrles on SourceForge or something that if e.g. I will 
want to submit a patch it would become simpler?
