%
%	HOW THIS CODE IS ORGANIZED
%
% In order:
%
%	- Required packages
%	- The blanks/noblanks option processing
%	- General Latex code required for the rest of the code
%
%	- Then code appears in the order its functionality appears in the documentation.
%

%		REQUIRED PACKAGES
%


\RequirePackage{changepage}
\RequirePackage{ifthen}
\RequirePackage{fmtcount}
\RequirePackage{tocloft}
\RequirePackage{geometry}
\RequirePackage{fancyhdr}



%
%		THE BLANKS/NOBLANKS OPTION PROCESSING
%


% The blanks/noblanks switch is in @handoutsBlanksFlag

}

%
%		GENERAL LATEX CODE
%

% These commands are used to define global variables.
% They are needed because a lot of the handout output commands are redefined in an if statement scope but need to be defined also outside of this scope.

%	1	BASIC IMPORT FUNCTIONALITY

	% However becuase the way Latex handles TOCs we can't use the command \thehandoutfulltitle directly.
	% So the following just manually adds the full title to the TOC.

%	3.2.1	THE HANDOUTS SUBDIRECTORY
%

%The directory in which the individual Latex files for each handout are stored
\newcommand{\thehandoutsdirectory}{handouts/}


%
%	4.1	TABLE OF CONTENTS STYLING
%


% This is the styling for the handouts table of contents.
% Styling done through the tocloft package.

% Set the TOC page to have empty page style
\tocloftpagestyle{empty}

% UNIT TOC ENTRIES
% Unit TOC entries in bold
\renewcommand{\cftsecfont}{\bfseries}
% This sets the bit that comes between the unit full title and the page number

% Align the page numbers to the left, next to the unit full title
\renewcommand{\cftsecafterpnum}{\cftparfillskip}

% HANDOUT TOC ENTRIES
% Handout TOC entries in italic

% This sets the bit that comes between the handout full title and the page number

% Align numbers on the left

%	4.2	SETTING UNIT TITLES
