Whitespace + docstring fixes
Further improve docstring
Extract first docstring paragraph instead of line
Show arguments on startup
Prefix reactor argument with underscore to clarify privateness
Prefix the other reactor argument with underscore to clarify privateness
Prefer namespace to be the first argument
Move pretty-printing functions out into a separate function; only treat optional args that start with _ as private
Move logic for accessing the remote attribute of the namespace (and raising a meaningful error when it doesn't exist) into a separate function
Use the new fancy refactored remote logic
