Clarify that ArchieML is converted to JSON

[JoeUX]

Hi all -- All the examples on the homepage show ArchieML input and JSON output, but nowhere is it mentioned that the output is JSON.

The spec never mentions the word JSON, but seems to assume JSON output.

Is output supposed to be JSON? If so, that's important, and should be articulated in many places. You could also spec it purely from a parsing standpoint, maybe an abstract tree, output-agnostic.
