The tools shows how to use control and data, and can work with any
ZIO input channel.

This is a working driver, with one cset and three channels that return
8-bit data. It is the demonstration that the ZIO abstraction is a good
way to avoid complexity in the low-level drivers.

This trivial trigger simply arms a timer to run zio_fire_trigger()
for a cset with a specified rate.  It is currently the default
trigger, until we have "app-request".

The file exports a few functions that can be used by specific buffers
to handle read, poll, release. Write is not supported at this time.

This is the default buffer: it manages a list of data blocks
(the lenght is fixed at 16 blocks by now) for any device and
any trigger.  The actual file operations in this case are
generic, and live in zio-buf.c (zio-core.ko).

These files are the heart of zio-core. The handle all issues of sysfs
and char devices (excluding the file operations.

These two headers devine the structures and operations for buffers
and trigger. Additionally, zio-buffer.h defines the control structure
and the data block.

This includes all the sysfs definitions and structures, together with
the main data structures for devices, csets and channels.

These files document how ZIO works. They are still subject
to modification while we are writing code, and some information,
for example how devices work, are still missing.
