Fixed a bug with how math is displayed in blog posts using MathJax.

  - $a$ was being turned into <span class="math">(a)</span>
  - I *think* it was because Pandoc was being used twice?
  - I fixed it by enabling \(\) for MathJax expressions in the Pandoc options
Continued working on my Tree Edit Distance blog post.

  - wrote a description of the basic string edit distance algorithm
  - implemented both a naïve and a simple dynamic version of the algorithm
Added a little page about laziness and Fibonacci numbers for my Strange Loop proposal.

  - wrote some basic text about the code example
  - added my two Fibonacci animations
  - still need to link to Tree Edit Distance blog post, once it is done
Added my array example to my fibs page as well.

  - wrote a bit of text about making dependencies explicit
  - added my array illustration too
