;****How to Merge two attributes in Datomic.****
;
;Our database has recorded two attributes for a user.  The user's e-mail and the users username.
;The username is required to be the e-mail for the user.  Due to a design decision, e-mails will no longer
;be recorded.  As such we need to depricate the e-mail attribute and merge it to our username attribute to ensure
;all e-mails represent usernames.
;
;The steps to this process are as follows:
;
;1. Rename the old attribute (i.e. :user/email to :user/email-deprecated)
