Workbook updates.

Workbook: complete updates to build.

Final round of fixes and updates for workbook to build correctly.
Added missing files, updated Makefile.

Major updates to workbook.

- Made the basemap figures smaller (they were too big and made the
compilation really slow).

- Changed the ratner figure from png to jpb (saved 90% in size)

- Removed all lyx files, we're now using pure latex.

- Added scripts for various useful tasks.
