traverse and filter X
E4X adds three basic operators. The dot (`.`) operator in E4X means "child"
and the `.@` operator means "attribute". The `..` operator means descendent. So
you can get all children with the name `child` by using `root.child` or an
attribute by using `root.child.@name` `root..child` will return all descendents
named "child" no matter how far down the hierarchy they are.
### Filtering
-E4X also allows filtering. Let's say you want to get only child who's name is
"Bob". You can do that by using `root.(child.@name == "Bob)`. To help grasp the
syntax, you can think of `.()` as a "filter function". The above expression in
English would be "give me all children of root whose name attribute equals
Bob". As you can see, the syntax is very concise, intuitive and quite powerful.

## Limitations
Because XML and E4X is not supported natively by the browser, some E4X code
needs to be rewritten by the compiler. For this to work, the compiler needs to
know that an object is XML. For this reason it's very important to be
consistent about declaring XML types in Royale. Particular care should be taken
if you have an array of XML objects to either use `Vector`, declare a local
variable (i.e. `var item:XML = arr[i]`) or use function access instead of E4X
syntax. To further clarify: `myUn [...]
