* Implement a coverage tool for collecting coverage data and generating code coverage reports on m-file functions and scripts. This would be very useful for Octave development as well as for users who want a code coverage report for their own functions and scripts.

* Implement test for plotting and graphics functions that might currently only have basic input checking and/or demos for human inspection.  Possibly create tests that probe properties of the handles created and returned by most such functions, such that test plots can be checked for correct feature size/location, etc.


We are far from even having one test for every function, so focus should be on getting the breadth of coverage first before trying to get the depth of 100% statement coverage.  As of Dec 2015, 202 of 1020 m-files have no tests.  Some of these will be plotting functions which have demos instead, but that leaves enough functions to be an interesting project.  As of Dec 2015, there are 485 instances of C++ functions which need tests.
