Power Feature: Document Inclusions

Doco has two types of includes - one happens before any Doco markup is parsed, and the other includes directly into the document directly before it's finalized to disk.

Both of them can take relative (to the source document location) and absolute paths.

 // include "relative/path/file.txt" before processing //
 // include "/absolute/path/Sample.java" before processing and indent //
 // include "relative/path/include.html" after processing //
 // include "/absolute/path/include.html" after processing //

If the file is not found, an error message is inlined into the document.

 *"The file <fileName> does not exist!"*
