Demo - User Settings
Use the "user_settings" API calls to make a "settings window"

or some other mechanism to map between PySimpleGUI keys and user settings keys.

"""
Creates a new window. The default values for some elements are pulled directly from the
"User Settings" without the use of temp variables.
Some get_entry calls don't have a default value, such as theme, because there was an initial call
that would have set the default value if the setting wasn't present. Could still put the default
value if you wanted but it would be 2 places to change if you wanted a different default value.
Use of a lookup table to map between element keys and user settings could be aded. This demo
is intentionally done without one to show how to use the settings APIs in the most basic,
straightforward way.
If your application allows changing the theme, then a make_window function is good to have
so that you can close and re-create a window easily.
