Command Function Invoker

Purpose

The command function invoker provides a host for functions implemented as a single executable command (be it a shell script or a binary). It accepts HTTP requests and invokes the command for each request.

Communication with the function is done via stdin and stdout. Functions can log by writing to stderr.
