Inputs to files nested within LaTeX document

1	inputs_of(filename, exclude.preamble = TRUE, append.tex = TRUE)

`filename`	The file whose `\inputs` are to be extracted.
`exclude.preamble`	(logical) If `TRUE`, the default, only `\input`s and `\include`s within the `document` environment are returned.
`append.tex`	Should the result include the file extension `.tex`? By default, `TRUE`. Setting to `FALSE` may be useful when the file is not a `.tex` file.

A character vector of file paths relative to filename that are used as \inputs or \includes within filename. If no such files are present within filename, NULL is returned.
