1. As Sumokoin forked Monero v0.10.1, most copyright notices reverted
to 'Copyright (c) 2014-2016, The Monero Project'

2. Some codes merged from upstream in 2017 were marked as 'Copyright (c) 2014-2017'

3. Sumokoin retained copyright at only a few places where we improved or largely
modified code logic like emission scheme, different calculation algo etc.

Thanks for advices from community to fix this and hope if someone find incorrect
any copyright notice somewhere, just submit an issue or email to devs rather than
to file DMCA takedown. Thanks.
