Editing BIST for m-files

== Overview ==

These m-files do not have built-in tests.

Sometimes this is because the function is interactive, like the inputdlg function, or reads data from a device like the @audiorecorder class, and would be very difficult to test.

Sometimes this is because the output is graphical, such as the plot routines, and would be difficult to test without image comparison routines.  These functions often have %!demo blocks instead.

Sometimes the function is an internal one (begins with "__" and ends with "__").  These functions don't usually need tests by themselves as they are called by another function which does have tests written for it.  Still it would be nice to remove these from the list by adding

 <nowiki>
 ## No test needed for internal helper function.
 %!assert (1)
 </nowiki>

to the internal function.

For the remainder, it's because no one has taken the time to write a test for them.

Before starting, take a look at Appendix B Test and Demo Functions and Appendix C Tips and Standards for what functions are available for testing and how to write code that conforms to Octave's coding guidelines.  Another good strategy is to look for %!test, %!testif, %!xtest blocks in existing m-files and see how they were coded.
