The file simple.h contains a few simple functions to demonstrate 
array handling and type conversion.  All of the functions are
'inline' so this example is as easy as possible to link--there should
only be one file which actually needs to be compiled.

Matlab notes:

	Type "make matlab" to make the demo for matlab.
	To run it, enter matlab and type the following:

	>> path('wrap_m', path);
	>> demo

Octave notes:

	Type "make octave" to compile it for octave.
	To run it, enter octave and type:

	octave:1> simple_stub
	octave:2> demo

Tela notes:

	Type "make tela" to compile it for tela.  To run it, do this:

	% tela_simple
	> source("demo.t")
