+/** Custom Compiler with phases for the documentation tool
+ *
+ *  The idea here is to structure `dottydoc` around the new infrastructure. As
+ *  such, dottydoc will itself be a compiler. It will, however, produce a format
+ *  that can be used by other tools or web-browsers.
+ *
+ *  Example:
+ *    1. Use the existing FrontEnd to typecheck the code being fed to dottydoc
+ *    2. Create JSON from the results of the FrontEnd phase
