finished User's Guide chapter 14.  Fixed an error where Clef could come before TimeSignature and what follows from that.  Restored Beaming code to Lilypond.  All in all, not bad...

git-svn-id: http://music21.googlecode.com/svn/trunk@3399 5c16147e-a200-11de-b0cc-ab0ad15e60d0
Added a local copy of the nbconvert tool to Music21's ext/ directory.


git-svn-id: http://music21.googlecode.com/svn/trunk@3400 5c16147e-a200-11de-b0cc-ab0ad15e60d0
buildDOc/ipynb2rst now uses music21's local version of nbconvert.py.


git-svn-id: http://music21.googlecode.com/svn/trunk@3401 5c16147e-a200-11de-b0cc-ab0ad15e60d0
Renamed IPython notebook conversion script.


git-svn-id: http://music21.googlecode.com/svn/trunk@3402 5c16147e-a200-11de-b0cc-ab0ad15e60d0
Added Python shebang to IPython notebook conversion script.

The IPython notebook conversion script now:

    - converts all notebooks found in buildDoc/ipythonNotebooks
    - removes unnecessary files from each notebook's generated *_files
      directory (all *.text files)
    - copies over all generated *.rst files to buildDoc/rst
    - copies over all generated *_files/ directories to buildDoc/rst *if*
      the folder does not already exist (because we don't want to hose the
      hidden .svn files if those folders had previously been versioned)
    - otherwise, it simply copies over the contents of the folder and removes
      the newly emptied folder from buildDoc/ipythonNotebooks

For the moment, just run the conversion script like this:

    buildDoc$ convertIPythonNotebooksToReST.py

If this proves acceptable, we'll hook this logic into the main doc building
workflow.
