Version 1.7
CHANGE - Now a configurable reminder email can be sent.
BUG - Fixed a date bug where the day of the year instead of the day of the month was used as the agenda date.
CHANGE - Refactored email sending into a more general case Runnable that can be used to send all sorts of emails.
BUG - Fixed a bug where 1stand3rd mode only ran agenda's based on 1st and 3rd Sundays of a given month.  Added a configurable day of the week for this calculation.
