Brix 310 mpl ui part2

1st, you are redefining `container` here.
2nd, why pass the method the container it should use if the code proceeds to ignore it?
3rd, we should **ALMOST NEVER** be using `d3.select` inside of a bric. In this particular case you are searching the document for the set of elements that have a class `codeExample`. Ignoring any other things that might be setting that class on an element, if you've got 2 CodeQuestion brix on a page you'll have at least 2 matching elements.

This is why in a bric we always use `this.lastdrawn_brixGroup.select()`

I suspect this is a problem of trying to make the method work in a way it is not designed to. If you want the code examples written somewhere other than the container for the responses, their should be a separate method to do that, and the code that is calling this method perhaps should call that one as well.
