Projects now contain a set of TextDocument objects. Each TextDocument represents a member file in the project. TextDocuments may not have their file contents loaded at all times, but they will be loaded on demand when calling TextDocument::contents(). "Find in files" works by iterating over the documents in the project and calling find(needle) on each one. The return value from find() is a vector of line numbers where the needle was found. This is obviously going to need a bunch more work. :^)
