Latest version, updated 11/01/2014.

Updated 4/21/2014. Some data sorting errors which had put some events in the wrong chronological sequence were corrected in this version. If you’ve been using an older copy of the spreadsheet, please update it by downloading the current version. All known errors have been corrected, but please let me know if you notice additional issues.
