Wiki and architecture

Following up on our meeting Wednesday, I added a section to the Wiki [1]
that talks to how I envision the pieces integrating with WPT.  My action
item out of Wednesday's meeting is to start the implementation process -
connecting the WPT environment to an AT "shim" that will communicate the
accessibility tree and AT events back to the running test.  I am looking
into various ways to achieve this. I am going to create a linked Wiki page
that captures that design as it evolves.  I look forward to all your input!
