Correctly set up subfiles

This might help with pandoc/epub conversions (#46)

FWIW, just keeping chapters in separate files doesn't require subfile.

Apparently, that package lets you compile chapters independently* — which is pretty cool (normally one has to resort to \include and \includeonly, which works but is pretty annoying). So if you don't use that feature, maybe dropping subfile is an (inconvenient) solution. (I suspect conditional compilation with the comment package might help disabling subfile when annoying, but this can be tricky—and pandoc wouldn't get it either).

From subfile docs (which I find on TeXLive through texdoc subfiles, recommended or on CTAN at http://ctan.mirror.garr.it/mirrors/CTAN/macros/latex/contrib/subfiles/subfiles.pdf):

With the subfiles set, the typesetting of a multi-file project consisting of one main file and one or more subsidiary files (subfiles) is more comfortable, since the user can LATEX either the main file, which will \input the subfiles normally, or the subfiles by themselves, which take the preamble of the main file and become self-sufficient LATEX documents.

(BTW checking it out, didn't know about it and would have been useful!)

I initially went with subfiles because I didn't want to put everything in one giant .tex file (to allow working on individual chapters separately). In addition, I had to add this:

milewski-ctfp-pdf/src/preamble.tex

Lines 94 to 103 in a3a74e0

	\usepackage{subfiles}
	\makeatletter
	\let\org@subfile\subfile
	\renewcommand*{\subfile}[1]{%
	\filename@parse{#1}% LaTeX's file name parser
	\expandafter
	\graphicspath\expandafter{\expandafter{\filename@area}}%
	\org@subfile{"#1"}%
	}
	\makeatother

so that the images could be embedded using relative path.

To rephrase: if you want just that, the main file just needs to use \input{chapter1}, without subfile, and \input just inlines the content of chapter1.tex.
EDIT: so for that goal subfile is indeed unnecessary.

Closing this for now. The way I have it set up lets me include relative images, and I don't want to spend anymore time on this.
