MD Project Summary for Things

Things from Cultured Code is great for keeping track of tasks and
projects.  But sometimes a report of what’s happened would be great.

This script pulls open and closed tasks from selected projects, then
opens the files in Marked 2 for use.
Merge branch 'master' of https://github.com/troypesola/things-md-project-summary
Configuration, comments, and license.

Time to move the output file to the top to make it easier to update.
Added more comments and the MIT license.
