Create documentation for simple library toolkit

Original idea from https://www.vipm.io/posts/01b17b9b-b230-4b89-8db4-7edaa057abdd/

A first version could work like that:

• Inputs:
  • Toolkit name
  • Version number
  • main menu file (*.mnu)
  • adoc file describing the purpose of the toolkit (optional)
• Document generated:
  • Title: Toolkit name (and version number)
  • Description Section -> adoc file content if provided
  • Functions Palette Section
    • one section for each palette/subpalette with the following content
      • Palette image
      • one subsection for each function with vi image + vi description
  • Controls Palette Section
    • one section for each palette/subpalette with the following content
      • Palette image
      • one subsection for each control with control icon + control description

NOTES:

• No handling of examples and tools provided by the toolkit
• The output needs to be rendered as HTML/PDF before being provided with the toolkit
