% Document Versions
%
% Version 1.2, 2017/02/26
%   Refactored the document to allow it to be used to write BSc Theses.
%
% Version 1.1, 2015/11/06
%		Updated document class so as to be compatible with the template file
%		regarding the appearance of headers/footers and appendix names. Require
%		also package `longtable' for being used for abbreviations/acronyms.
%
% Version 1.0, 2014/12/08
%		Initial attempt at creating the first class file for LaTeX Theses in
%		DI&T, NKUA.

% Known Issues
%
% * Chapter titles are not appearing in capital letters in the ToC, although
%   in other places this has been taken care of for good. Thus, one is enforced
%   to type chapter titles in capital letters, so as to be compatible with the
%   requirements of the department.
