$.template() can render multiple languages

Scripts with different types have different meanings

• type="text/html" renders as HTML in-place
• type="text/plain" renders as text, i.e. set the innerText, not innerHTML
• type="text/markdown" - Markdown
• type="text/vega" - Vega
• type="text/vega-lite" - Vega-lite
• type="text/plotly" - Plotly
• type="text/echarts" - echarts
• type="text/mermaid"- mermaid graph
• type="text/flowchart" - flowchart
• type="text/js-sequence" - js-sequence
• etc.

Implementation:

• Each works as a plugin that can be registered independently, and can be extended. text/html will use _.template for example.
• To allow use of </script> tags for code examples, the container can be <template> instead of <script>
