Previously, there was a confusing mix of functionality shared between
the two wherein you would need to use the Kong type for printing errors,
etc. but it did not have access to the context in order to print
context-sensitive usage information. This has been fixed.
Additionally, there are now fuzzy correction suggestions for flags and
commands
Also added a server example which shows how Kong can be used for parsing
in interactive shells. Run with:
$ go run ./_examples/server/*.go
Then interact with:
$ ssh -p 6740 127.0.0.1
This allows help to be called even when the parse trace is invalid.
Without this, the command-line would have to be valid in order to use
help at all, which defeats the purpose.
