Add an easy way to initialize.

Jeez, this whole thing could *almost* go away if we moved to flash 10
and used Vector, but of course, there's no way to get the type of
Vector. Maybe there is, with describeType(). Can't experiment now.
I'd fall out of my chair if there were.
We need to know in case sending an empty array to the server,
it's still gotta be the right type (with non-empty we could
try examining the first element).
