Module requirements:

• Zend Form to extend
• Parsedown for PHP side parsing to HTML
• ShowdownJS for client side parsing to HTML for preview
• AssetManager to inject JS with ViewHelper

Features

• Provides Service (MarkdownService) for handling markdown conversion server-side
• Provides a ZF Form Element (Markdown) for Form input
  • Provides Showdown to client when using Markdown Form Element

TODO's

• Create better preview - possibly:
  • option: inject some overridable default styling
  • option: side-by-side preview instead of above/below
  • option: minimum (overridable) styling to always have a visible preview container
• Figure out incompatibilities between Parsedown and ShowdownJS
