Incomplete documentation for Core Modules and Cmfive Tests

The menu for Core Module documentation lists all of the core modules, however only the Introduction, Insight, and Report documentation pages have been linked. Cmfive Tests is mostly complete except for the Running Tests and Writing Tests documentation pages.

Review the menu structure in the documentation site to identify which core module links are missing. Locate the existing documentation files for Introduction, Insight, and Report to understand the format. Then, find or create the corresponding pages for the other core modules and the missing Cmfive Tests pages (Running Tests and Writing Tests). Ensure all new pages are properly linked in the menu.
