Access to cpp.Struct fields when wrapped as Dynamic (and in cppia?)

[kevinresol]

Let's say Native is a c++ struct with a float foo field.

final n:Native = allocNativeSomehow();
final s:cpp.Struct<Native> = n;
trace(n.foo); // works
final d:Dynamic = s;
trace(d.foo): // null

It would be nice to generate a Dynamic wrapper for each cpp.Struct with proper reflection support. And I assume it is possible (?) because the type information of Native is known by Haxe at compile time.

I also assume that would enable access to cpp.Struct from cppia as well?
