Shop Interface
==============
For interacting with various shop interfaces.
All may not work, but I think most should work. There's a good chance the only
thing lacking is that title of your shop interface, so if it doesn't work add
the shops title - or a subset of it by doing

.. code-block:: pascal

 ShopScreen.AppendTitle('Wallmart');

PS: You are expected to find and open the interface yourself.

.. code-block:: pascal

 var ShopScreen: TRSShopScreen;

ShopScreen.__Setup
~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: pascal

 procedure TRSShopScreen.__Setup();

ShopScreen.__Prepare

.. code-block:: pascal

 function TRSShopScreen.__Prepare(): Boolean;
