func_documentation_string: Creates classical styled `toString` method;  E.g. `toString` method that returns
  `'[object ' + constructor.name + ']'` a` la` '[object Array]', '[object Function]' format.
  @fyi method is a named function (named `toStringOverride` to be precise).
  @note Only overrides `toString` method if it is a `named` method with the name `toString` or
  if it doesn't exist.  If the `toString` method is `named` and the name is anything other than 'toString'
  it will not be overridden by this method.

  @returns {Function} - Passed in constructor.
