Added some new tests and two new files for testing: test_types.py

(testing operations on built-in types) and autotest.py (automatic
regression testing).

+# Automatic Python regression test.
+#
+# Some essential parts of the Python interpreter are tested by the module
+# 'testall'.  (Despite its name, it doesn't test everything -- that would
+# be a truly Herculean task!)  When a test fails, 'testall' raises an
+# exception.  When all tests succeed, it produces quite a lot of output.
+#
+# For a normal regression test, this output is never looked at unless
+# something goes wrong.  Thus, it would be wise to suppress the output
+# normally.  This module does that, but it doesn't just throw the output
+# from 'testall' away -- it compares it with the output from a previous
+# run.  If a difference is noticed it raises an exception; if all is well,
+# it prints nothing except 'All tests OK.' at the very end.
+#
+# The output from a previous run is supposed to be in a file 'testall.out'
+# somewhere on the search path for modules (sys.path, initialized from
+# $PYTHONPATH plus some default places).
+#
+# Of course, if the normal output of the tests is changed because the
+# tests have been changed (rather than a test producing the wrong output),
+# 'autotest' will fail as well.  In this case, run 'testall' manually
+# and direct its output to 'testall.out'.
+#
+# The comparison uses (and demonstrates!) a rather new Python feature:
+# program output that normally goes to stdout (by 'print' statements
+# or by writing directly to sys.stdout) can be redirected to an
+# arbitrary class instance as long as it has a 'write' method.
