See ../README for common README file.

Any testcases which have _runme.ss appended after the testcase name will be detected and run.
NOTE: I had to use _runme.ss becuase otherwise it would be hard to implement make clean
Since when SWIG runs it generates an example.scm file for every test, to clean those files
I needed to add a rm -f *.scm to make clean.  But we don't want the runme scripts to
dissappear as well!
