knitr hook functions are called when the corresponding chunk options
are not NULL
to do additional jobs beside the R code in chunks.
kfigr provides the hook "anchor" which adds an HTML anchor tag
immediately above a code chunk.

the function hook_anchor is set as a hook in knitr when
kfigr is attached (and removed when kfigr is detached). It
writes an HMTL anchor tag directly above a code chunk in the form
<a name="chunk-name"></a>
where chunk-name
is the chunk
label contained in options$label
.
