@nkolba I have removed the second part - seems like an implementation detail to me. FDC3 has no concept of "windows", so it shouldn't be in there.

Addresses #121.
A summary of the type changes I introduced:
becomes:
The channel parameter is completely redundant here, as we already now what the channel is from the owning object - if a reference is needed, it can be captured with a closure. This brings the handler in line with the one on the desktop agent, which makes for much easier consumption.
Apart from that I have factored out and improved the relevant documentation sections on the website.
