Hello,

I am wondering how can I make your Google Doc plugin compatible with tikz-bayesnet https://github.com/jluttine/tikz-bayesnet

to be able to render these graphics

With this kind of code

```
\usepackage{tikz}
\usetikzlibrary{bayesnet}
\begin{tikzpicture}
\node[latent] (theta) {$\theta$} ; %
\node[latent, right=of theta] (z) {$z_n$} ; %
\node[obs, right=of z] (y) {$y_n$} ; %
\node[latent, above=of z] (mu) {$\mu_k$} ; %
\node[latent, above=of y] (sigma) {$\sigma_k$} ; %
\plate[inner sep=0.25cm, xshift=-0.12cm, yshift=0.12cm] {plateN} {(z) (y)} {$N$}; %
\plate[inner sep=0.25cm, xshift=-0.12cm, yshift=0.12cm] {plateK} {(mu) (sigma)} {$K$}; %
\edge {theta} {z} ; %
\edge {z} {y} ; %
\edge {mu, sigma} {y} ; %
\end{tikzpicture}
```

While it can render the graphics, it throws an error, whenever I click on that image so I cannot edit it anymore

Thanks
