# Used for notifing users with emails about different events

# Ex.
# NotificationService.new.new_issue(issue, current_user)

# only if ssh key is not deploy key
#
# This is security email so it will be sent
# even if user disabled notifications

#
# * issue assignee if his notification level is not Disabled
# * project team members with notification level higher then Participating
