JUnit Engine for Markdown-based tests.

By default, the engine will scan for markdown files within doc/.
To override this, use the markdown-junit-engine.markdown-files-root-path property.

By default, the engine will use the com.github.fridujo.markdown.junit.engine.visitor.provided.CodeBlockCompilerVisitor which compiles all code blocks with the Content-Type java.
To specify a custom MarkdownVisitorFactory, use the markdown-junit-engine.markdown-visitor-factory-class property.

The provided factory must return an implementation of MarkdownVisitor which will

• First, be notified of each Markdown AST element
• Then, queried for TestNode to process as part of the JUnit execution tree

A TestNode can either be a ContainerNode or a RunnableNode.
