Scenario: Provide summary for a section (subdirectory)
Given the "SUMMARY.md" in the "authentication" subdirectory with Markdown
"""
Authentication
==============
The Markdown-powered summary of the `Authentication` section
"""
And the "SUMMARY.md" in the "admin" subdirectory with Markdown
"""
Admin

"""
When I serve the directory as a system specification
And open it in my web browser
And click the "Authentication" node in the features tree
Then the summary from "authentication/SUMMARY.md" should be parsed and displayed
When I click the "Admin" node in the features tree
Then the summary from "admin/SUMMARY.md" should be parsed and displayed
