[Yaml-core] Work done

[Oren Ben-K. <or...@ri...>]

OK, I just spent most of the day editing the latest spec. I did horrible
things to it, such as restructuring, ane re-wording, ans fixing examples,
and removing an unnecessary production, and I don't quite recall what else
:-)

At this point I can't bear to look at it any more ;-) so I'm handing it off
to you, Clark. Have Claudia wield her red pen and wreak your favorite havoc
on whetever remains...

BTW, two issues:

- I think the TOC is missing some entries. I only noticed it now as I'm
sending it...

- Your examples used $1,234.56 which is doubly illegal. I changed it to
1234.56, but... do we want to go to the "fixed precision" land? We also
don't allow for 123.123.123.123 IP addresses and probably lots of other
application-specific types - perhaps it is best to leave it as it is and add
it later in yaml.org.

I think it is looking really good now... 

Have fun,
