We've added examples for this. For embeds and loadings.
RM also has events, why not use them by default? This would probably spare you
headhackes in the long run...
Also, another tip: avoid addChild anything before its there. Even if its in
there for the convenience or better said, implemented because it can be handy
in some cases,
it is a safer practice to addChild an object when you know it's there for sure.
After all, what is the point of addChilding an empty container if it turns out
the server can not find the url for instance?
In this particular class, it is not a big deal of course, as you can locate
your potential resource loading problem very fast, but if you were dealing a
more complex scenery, it might cost you headackes again, simply because your
code assumes it's there.
