Preserve YAML comments when roundtripping...

[GoogleCodeExporter]

We use YAML as a configuration language in our Okapi localization framework
(http://code.google.com/p/okapi/) - it would be great if SnakeYaml could
preserve our comments when we load then dump our yaml files. Otherwise
SnakeYaml dump is very clean!

It is the same as the issue for PyYAML:
http://pyyaml.org/ticket/114

Since there is no easy and clean solution I would recommend to discuss the 
problem in
yaml-core mailing list.

Can you please show an example of the YAML file where you wish to keep the 
comments ?

It is a rather complex hierarchy of comments. I see a few possible solutions:
1) custom dumper
2) annotations
3) settings similar to TypeDescription
Any approach would require a considerable code change in SnakeYAML. I think we 
shall 
try all approaches to see the impact on the code.
I will have a deeper look once I have more time.
