Make a makefile to build MISs after MGs

[niazim3]

As mentioned in #61, the generated document makes it appear as if the links are broken from section 3 to the Module Guide (

caseStudies/CaseStudies/ssp/Documentation Files/MIS_SSP.tex

Lines 157 to 165 in 0f4f403

	% ---------------------------------------------------------------- %
	% --------------------- MODULE GUIDE --------------------------- %
	% ---------------------------------------------------------------- %
	\section{Module Guide}
	The module decomposition can be found in table \ref{MG-Table:Decomp},
	and the module use hierarchy in figure \ref{MG-Fig_Use} of the MG.

).

@smiths Explained, however, that
"The links are external, so the MG has to be compiled first. The MIS uses the xr (external reference) package:

https://www.sharelatex.com/learn/Kb/Cross_referencing_with_the_xr_package_in_ShareLaTeX

I asked the previous students to write a makefile that would ensure that all of the documentation is up to date, since there are dependencies between the files. I do not believe that anyone has written that script. For now, we'll just have to manually make sure to compile all of the documents when the xr package is in use."

Making a makefile that does this may be helpful in the future.
(Unsure who to assign this to, so assigning myself for now...)
