A preprocessor for mdbook to add mermaid.js support.

It turns this:

```mermaid
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
```

into this:

in your book. (Graph provided by Mermaid Live Editor)

If you want to use only this preprocessor, install the tool:

cargo install mdbook-mermaid

Then let mdbook-mermaid add the required files and configuration:

mdbook-mermaid install path/to/your/book

This will add the following configuration to your book.toml:

[preprocessor.mermaid]
command = "mdbook-mermaid"

[output.html]
additional-css = ["mermaid.css"]
additional-js = ["mermaid.min.js", "mermaid-init.js"]

It will skip any unnecessary changes and detect if mdbook-mermaid was already configured.

Additionally it copies the files mermaid.css, mermaid.min.js and mermaid-init.js into your book's directory. You find these files in the src/bin/assets directory.

Finally, build your book:

mdbook path/to/book
