Unfortunately, I can't REALLY extend the Date class because it's declared
final (thanks a lot, guys). But here's my replacement for it. It wraps all
the same functions as Date exposes by sending them to an internal Date
object. It also adds a built-in formatter and a format() call. In
addition, there's an asString property which helps a lot in the Expressions
tab during debugging. Oh, and I've extended the formatter to interpret
"SSS" as zero-padded milliseconds (something strangely lacking in
DateFormatter). Just thought some people might make use of this simple
class. It's not something you'd use in a performance critical situation,
but then again, neither is the original Date class.
