Addition of Copyright Notice

[lubovtorina]

Hello! According to the Appendix of Apache License 2.0, if you want to license your software under this License you should "attach the boilerplate notice, with the fields enclosed by brackets "[]" replaced with your own identifying information". This condition is not met now.

Сould you add a COPYRIGHT NOTICE FILE in the appropriate form, including the year of the software development and your name and surname? You could also apply the Apache License to your source-code files by attaching the notice as a comment at the top of each file. Thank you in advance! Apache.org says: Include a copy of the Apache License, typically in a file called LICENSE, in your work, and consider also including a NOTICE file. It is also valuable to tag each of your source-code files in case they become detached from the LICENSE file. To apply the Apache License to your source-code files, one approach is to attach the following notice to as a comment at the top of each file. Replace the copyright templates with your own identifying information:
