Ignore some auxiliary files from knitr

[adamliter]

knitr is an R package that can be used to compile a .Rnw file containing both LaTeX and R source code to a .tex file, which can then be further compiled to a .pdf file with your favorite TeX engine. When the R source code generates images (e.g., a graph), it will create some auxiliary files, including .tikz file(s) and a BASEFILENAME-tikzDictionary file (at least if the dev chunk option is set to 'tikz'). Additionally, if opts_knit$get('concordance') is TRUE, then an auxiliary BASEFILENAME-concordance.tex file is generated. None of these things need to be tracked with version control.

Some more information on the -concordance.tex file, quoted from here:

a concordance file [...] map[s] the output line numbers to the input line numbers; this enables one to navigate from the output to the input and can be helpful especially when TeX error occurs (this feature is mainly for [the IDE] RStudio)

This is basically to say that the -concordance.tex file is really only for debugging purposes, so it doesn't make sense to track it with git.

Thanks for this! ✨
