 Transport (structured)

-While a `Channel` transports blobs and/or native handles, it is likely the Flow-IPC user will want to be able to transmit schema-based structured data, gaining the benefits of that approach including arbitrary data-structuree complexity and forward/backward-compatibility.  [capnp (Cap'n Proto)](https://capnproto.org) is the best-in-class third-party framework for schema-based structured data; ipc::transport's structured layer works by integrating with capnp.

 To deal with structured data instead of mere blobs (though a schema-based structure can, of course, itself store blobs such as images), one simply constructs an ipc::transport::struc::Channel, feeding it an `std::move()`d already-opened @link ipc::transport::Channel Channel@endlink.  This is called **upgrading** an unstructured `Channel` to a `struc::Channel`.  A key template parameter to `struc::Channel` is a capnp-generated root schema class of the user's choice.  This declares, at compile-time, what data structures (messages) one can transmit via that `struc::Channel` (and an identically-typed counterpart `struc::Channel` in the opposing process).

@@ -71,7 +71,7 @@ The simplest thing to do (though, again, we do not recommend it, as it's giving
 The next simplest thing, and likely suitable at least for prototyping situations, is to output Flow-IPC logs to stdout and/or stderr.  To do so construct a `flow::log::Simple_ostream_logger` (near the top of your application most likely), passing in the desired verbosity `enum` setting to its constructor's `Config` arg; plus `std::cout` and/or `std::cerr`.  Then pass-in a pointer to this `Logger` throughout your application, when Flow-IPC requires a `Logger*` argument.  Logs will go to stdout and/or stderr.  (However beware that some log interleaving may occur if other parts of your application also log to the same stream concurrently -- unless they, too, use the same `Simple_ostream_logger` object for this purpose.)
 
 If your application is not based on `flow::log` (which of course is very much a possibility) then you will, longer-term, want to instead hook up your log system of choice to Flow-IPC.  Don't worry: this is not hard.  You need to implement the `flow::log::Logger` interface which consists of basically two parts:
-  - `bool should_log()` which determines whethere a given message (based on its severity `enum` and, possibly, `Component` input) should in fact be output (for example your `should_log()` might translate the input `flow::log::Sev` to your own verbosity setting and output `true` or `false` accordingly).
+  - `bool should_log()` which determines whether a given message (based on its severity `enum` and, possibly, `Component` input) should in fact be output (for example your `should_log()` might translate the input `flow::log::Sev` to your own verbosity setting and output `true` or `false` accordingly).
   - `void do_log()` which takes a pointer to the message string and metadata info (severity, file/line info among a few other things) and outputs some subset of this information as it sees fit.  For example it might forward these to your own logging API -- perhaps prefixing the message with some indication it's coming from Flow-IPC.
 
 Lastly, if your application *is* based on `flow::log` -- or you would consider making it be that way -- then we'd recommend the use of `flow::log::Async_file_logger`.  This is a heavy-duty file logger: it performs log writing asynchronously in a separate thread and is rotation-friendly.  (It even will, optionally, capture SIGHUP itself and reopen the file, so that your rotate daemon might rename the now-completed log file, moving it out of the way and archiving it or what-not.)  `Async_file_logger` is meant for heavy-duty logging (and as of this writing may be gaining more features such as gzip-on-the-fly).
