Factory callable to be used when creating new grid instances; defaults to
:class:`tailbone.grids.Grid`.
.. Methods to Override
.. -------------------
..
.. The following is a list of methods which you can override when defining your
.. subclass.
..
.. attribute:: MasterView.help_url
If set, this defines the "default" help URL for all views provided by the
master. Default value for this is simply ``None`` which would mean the
Help button is not shown at all. Note that the master may choose to
override this for certain views, if so that should be done within
:meth:`get_help_url()`.

May return a "help URL" if applicable. Default behavior is to simply
return the value of :attr:`help_url` (regardless of which view is in
effect), which in turn defaults to ``None``. If an actual URL is
returned, then a Help button will be shown in the page header;
otherwise it is not shown.
This method is invoked whenever a template is rendered for a response,
so if you like you can return a different help URL depending on which
type of CRUD view is in effect, etc.
