[issue10273] Clean-up Unittest API

[Raymond Hettinger]

New submission from Raymond Hettinger <rhettinger at users.sourceforge.net>:

* Dedocument assertSetEqual, assertDictEqual, assertListEqual, and assertTupleEqual.  These are all automatically dispatched from assertEqual.  The user need not call any of these directly.  These methods should not have been exposed in the docs.

* Add new names and dedocument old names for assertLess, assertLessEqual, assertGreater, assertGreaterEqual.   The new names are modeled after the gt, le, lt convention used elsewhere in the language.  This avoids to problems remembering the current spelling quirks (dropping the Than in LessEqual, pluralization, camel casing, being too long, etc).  New names will be assertLE, assertLT, assertGE, and assertGT.

* Add news names and dedocument assertRegexpMatches and assertNotRegexpMatches.  These names haves have multiple issues (they actually do a re.search not a re.match, they are long, the pluralization is inconsistent with the assertEqual convention, they don't agree with the names used in other unittest implementations such as PHPunit and Junit).  The new names will be assertRegexp and assertNotRegexp.

* Remove the assertItemsEqual method (which is new in 3.2).  Its semantics are not obvious from its name (i.e. duplicates matter, order does not matter, expects elements not items, has O(n**2) behavior after an impending bug fix, uses on equality for matching not hashing or ordering).  In most common cases, it is more explicit and flexible to use assertEqual after casting to a set, a list, or sorted list.  Also note that other unittest implementations such as PHPunit and JUnit do not have this method.  See http://mail.python.org/pipermail/python-dev/2010-October/105073.html 

* Recombine the package into a single file.  See http://mail.python.org/pipermail/python-dev/2010-October/105025.html and http://mail.python.org/pipermail/python-dev/2010-October/104887.html

* We need to review the camel cased spelling on two methods that are new in 3.2.  Should it be assertIsinstance or assertIsInstance?
