Sketching the mvg idea out with a prototype.
Sketching the mvg idea out with a prototype.

For now, I have changed the bin file dump to stdout the
resulting mvg file.  Usage is (temporarily):
  $ bin/chronoplan example/schedule_example.txt > test.mvg
  $ convert -background none test.mvg test.png
which generates the transparent overlay as test.png

There are several things left if we decide to persue this route:
  - Move the templates to a separate file rather than storing them
    in the code.
  - Move the arithmetic out of the template (Maybe? What's the "ruby
    way" here?)
  - Create a vectorized Chronodex representation as an mvg, and
    move the calls to ImageMagick back into lib/chronoplan.rb
  - Verify that transparency works in mvg.  I cannot tell, from
    what I have, whether or not it is recognizing the alpha channel.
