Checks for common latex mistakes

[suyashmahar]

Some of our published papers have mistakes where

1. Figure is not referenced in the text
2. References are missing (?) in the paper

Latex warnings are next to useless in most cases since they are hidden in a wall of text. Maybe we should -Werror or something in submission mode (#12)

latexmk supports werror:

   -Werror
         This causes latexmk to return a non-zero status code if any of the files processed gives a warning about  problems  with  cita‐
         tions  or references (i.e., undefined citations or references or about multiply defined references).  This is after latexmk has
         completed all the runs it needs to try and resolve references and citations.  Thus -Werror causes latexmk to treat  such  warn‐
         ings  as errors, but only when they occur on the last run of (pdf)latex and only after processing is complete.  Also can be set
         by the configuration variable $warnings_as_errors.
