Render docs for methods by default

We should render docs for methods by default rather than requiring showdoc(...) on each method. Of course its better if people use showdoc(method) as that promotes better docs, but perhaps for people starting out it can help with initial setup?

No file, test, or entry point is named. Start by locating the implementation and tests for showdoc(method), then compare default rendering with explicit showdoc(...). Done means method documentation renders without requiring showdoc(...) while the existing explicit usage remains supported.
