adding an offset to the tf doesn't even work?
moved Control Response section to start of Appendix
got a Control Law example working, by intuition...

Difficulties have been encountered getting a Control Law
example working due to its particular requirements and
the characteristics of the engine model.  Specifically
the control input should reflect the output and it should
stabilize at zero for negative feedback to work.

An example has been designed intuitively.  Simply by making
the correct compensation to G(z) and choosing some K to
be feed back.  It is not the fastest, but it works and it
is stable.
documented Control Law intuitive design

The Control Law intuitive design has been fully documented
with block diagrams and plots.
cleaned up Control Law, Intuitive Design section

General cleanup of the wording for the Control Law,
Intuitive Design section.  And removed some old
disabled sections.
added Colophon

A Colophon has been added that describes how this
document was designed.  The References section has
also moved to the end of the document.
Control Law on engine model still isn't working

Several attempts have been made to try and get
a Control Law with full feedback working with the
engine model.  But the non-zero stable point and
input/output offsets have created difficulties
that haven't be resolved yet.
Merge branch 'master' into matlab
Matlab incompatibilities, Simulink diagrams

Fixed several Octave to Matlab incompatibilities.
  - removed 'endfunction'
  - removed 'endfor', replaced with 'end'
  - Matlab does not support default function arguments,
    used 'narg' instead.
  - Matlab accepts 'InputName' instead of 'inname' and
    'OutputName' instead of 'outname' in the control toolbox.

Simulink diagrams for the Control Law Full Feedback examples has
been added.  The results are identical to the script only version.
Still haven't determined why they are incorrect and stabilize at
incorrect values.

Matlab does not support z-domain to state space conversion as well
as Octave. The resulting Phi and Gamma do not agree.
