[antlr-interest] parsing performance

While you are considering constructors how about adding a constructor which
accepts either a string or a byte array?  This would save me from having to
convert a string into a ByteArrayInputStream.

Ouch.  Dang!  I'll look at the API, but this is something we could use
by making a new constructor on the lexer to take a different kind o
stream, right?
