Moved test_xmlparser.py and xmlparser.py to the scripts directory and, more importantly,
updated the parse method to all for obstacles of 3 or more points.
Updated the test case for too few points.
Fixed a bug in the parse method.
Only have one robot in the "good" test file.
Modified the XMLParser import to match the current directory structure.
xmlparser is currently on same level as test_xmlparser.
Added code to parse the config file (XML).  Added unit test for the
read_config method.
Updated the unit tests so that they can be run outside the Eclipse project
in which I was working.  Tests can now be run from the command line.
