+ convert to using Pillow/PIL
+ add requirements.txt file
+ update umbrellas-grid.png

  This version of the grid image was created by the version
  of mosaic.py that uses the Pillow/PIL library.

  This version seems to give more similar results to Delta909's
  deviantART images:

+ add BSD License text
+ formalize project and repo structure

  - This setup was based on:

    http://kennethreitz.org/repository-structure-and-python/
+ include 'nose' as an external requirement
+ places example images into the tests directory
+ add some basic tests
+ add a 'make clean' directive

  - remove the compiled "*.pyc" bytecode files
+ formalize command line script invocation
+ don't exclude the bin directory!
+ specify the package dependencies
+ include non-python files with setup.py

  - this includes the 'README.md' and 'LICENSE' that is being
    parsed and added in setup.py
   - the 'package_data' attribute seems to be unreliable.  Need
     to specifically add the 'MANIFEST.in' file. See:

     http://stackoverflow.com/questions/1612733/including-non-python-files-with-setup-py
+ ensure that python 2.7.x is being used
+ flush out the README
+ remove an old debug statement
