This Month with Nim: November

[xigoi]

Thanks to the curators for approving my article about xidoc, and to 
@pietroppeter for your kind words! If you'd like to turn my wrappers around 
KaTeX and Prism into a library, you're welcome to do so. Just keep in mind that 
they're quite rudimentary and made with only xidoc in mind, so you'll need to 
make some improvements.
