moved test/test.py to test/testSingleCoreAll.py so that test.py in
braille/ etc. will run
fixed further changes resulting from test.py to testSingleCoreAll.py
rename.
all braille tests now pass -- the change to not allowing in-module
references in doctests broke many tests that omitted "test.exampleXX"
and because this file wasn't being tested this was missed.
fixed toMxObjects to support sus add 9, etc.
small fix on harmony to include more tests.
