;; Currently on evaluation this returns raw LaTeX code, however at
;; some point it *may* (it may not) make sense to have LaTeX blocks
;; compile small pdfs on evaluation.
;; Currently on evaluation this returns raw LaTeX code, unless a :file
;; header argument is given in which case small png or pdf files will
