  Liquid template for generating Java Visualizer embeds.

  Usage:
    {%- capture HelloWorld -%}
    public class HelloWorld {
        public static void main(String[] args) {
            System.out.println("Hello, world!");
        }
    }
    {%- endcapture -%}
    {% include java_visualizer.html code=HelloWorld caption="Hello, world!" %}

  Advanced usage:
    {%- capture HelloWorld -%}
    public class HelloWorld {
        public static void main(String[] args) {
            System.out.println("Hello, world!");
        }
    }
    {%- endcapture -%}
    {% include java_visualizer.html mode="display" code=HelloWorld
        caption="Hello, world!" label="Visualize Code" class="btn" curInstr="0"
        args='["arg1", ...]' stdin="stdin" showStringsAsObjects=""
        showAllFields="" disableNesting="" verticalLists="" %}
{% endcomment %}

{% assign mode = include.mode | default: 'display' %}
{% assign code = include.code | default: '' %}
{% assign caption = include.caption | default: '' %}
{% assign label = include.label | default: 'Visualize Code' %}
{% assign class = include.class | default: 'btn' %}
{% assign curInstr = include.curInstr | default: 0 %}

{% assign verticalLists = include.verticalLists | default: '' %}

{% capture codeBlock %}
```java

```
{% endcapture %}
{% assign codeBlock = codeBlock | markdownify %}
