Send email
Optional - Send email formulas requires OAuth2 & cron e.g. =email(to, subject, body), =emailAt(time, to, subject, body)
OAuth2 - Set environment vars
1) Tutorial: follow the tutorial to get the 4 environment vars http://masashi-k.blogspot.com.au/2013/06/sending-mail-with-gmail-using-xoauth2.html
2) Set 4 environment vars - see [src/emailer.ls] vars: user, clientId, clientSecret, refreshToken
Tested using gmail, have not tested with other providors
Cron - Required for emailAt formulas.
See *curl* in [.openshift/cron/minutely/timetrigger] for openshift version (openshift](openshift.redhat.com)
The curl checks the database for unsent emails and updates the database after sending.
