The script implementation has now been ported over to these new SPIs and all
seems to be ok and the calculator-script sample works now. The new SPIs seem
to me vastly better than what we had before. There's still some things I
think could be done to make it even easier to write an implementation, in
the script impl I've pulled out a few classes into a separate spi package
for code I thought the script impl shouldn't need to code itself, and theres
also a few TODO comments in the rest of the code. Code people take a look
and comment on those classes and TODO comments to see if there's things we
could improve?

Hi,

We now get the java component and echo binding working with the extension
interfaces. Please see the calculator and echo-binding sample.

Thanks,
Raymond
