Fix more typos.
Merge pull request #3 from mlang/master

Found some more typos.
Fix a few failing tests in music21.braille.test.

Some were missing the "test." prefix when calling the example function.
Others use .pop(0) to remove the time signature after makeNotation,
which does not do what the code expects.  It actually pops the clef.
Since the time signature is essential for reading braille music anyway,
stop trying to remove the time signature and include it in the example output.

This fixes 13 out of 48 failing tests.
moved test/test.py to test/testSingleCoreAll.py so that test.py in
braille/ etc. will run
Merge pull request #4 from mlang/master

Fix a few failing tests in the braille module.
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.
Fix most of the remaining test failures in music21.braille.test.
