%
% This package redefines the \maketitle macro for creating the inner titlepage.
%
% The basic usage is to define the title and subtitle using the \title and
% \subtitle macros followed by a call to the \maketitle macro:
%
%   \title{An Important Topic Worth Writing About}
%   \subtitle{A Very Important Report}
%   \author{John Doe | 0000001, Jane Doe | 0000002}
%   \course{[TU0000] A Very Futuristic and Challenging Course}
%   \supervisor{Dr. Jan Jansen}
%   \abstract{A summary of the document}
%   \maketitle
%
% Note:
%   The calls to \course and \abstract are optional. However, make sure to
%   call \maketitle within a document environment i.e. after calling
%   \begin{document}
