[gnuastro-commits] master ce208fe 1/2: Updated copyright information

From: Mohammad Akhlaghi
Subject: [gnuastro-commits] master ce208fe 1/2: Updated copyright information
Date: Thu, 25 Jan 2018 09:33:37 -0500 (EST) 
branch: master
commit ce208fe4bc5dac0f4d297327d418dbed565e6fa8
Author: Mohammad Akhlaghi <address@hidden>
Commit: Mohammad Akhlaghi <address@hidden>

    Updated copyright information
    
    2018 was added as the final copyright year in all the files with a
    copyright year. For those that already had a single year, that was changed
    to a format of `AAAA-BBBB' where `AAAA' is the year the file was created
    and `BBBB' is (currently) 2018. This will allow automatic scripts to update
    the last year automatically from the next year.
    
    My email address was also updated to address@hidden' from the old
    address@hidden'.
