Work for #1866 

Migrates all the public class docs over to appledoc format.  While Xcode is fine with blank lines in `///` comments, appledoc (used by cocoadocs) isn't and was leaving a bunch of info off the doc pages.

can reasonably be expected to be interoperable.

(The fact that not all Int64/Uint64 values *can* be exactly represented in

reason for wrapping them when we serialize... it shouldn't be a surprise that
we can't round-trip in unwrapped form for all values.)
