Updated README.md
Removed a rough draft of a cover letter, focusing this repo on my resume only.
Updated Skills to add .Net and knitr.
Updated experience. Specifically, I enhanced the detail in the HZA
portion of my resume and dropped some detail from older entries that
are honestly less important now.
Rearranged HZA experience section to make that section focus more
succinctly on my experience with HZA.
Removes the updates line. Unnecessary because the file is under
version control.
Updates Skills section.
Adds README.org, which replaces README.md
Changes the description of my time with HZA. Now includes a set of
sample / example projects.

Sample projects (bulleted) and an enhanced explanation of my efforts
to professionalize our analytic methods.
Finalizes my recent changes to my HZA description.

- Example projects are now bulleted and more detailed.
- Expanded description of my changes to HZA's workflow.
