Options Filter/Function about wds-simple-page-builder

[jazzsequence]

If this is a sort of initial setup-type function, I'm thinking it would work similar to register_page_builder_layout, i.e.:

wds_register_page_builder_options( array(
     'parts_dir' => 'parts',
     'parts_prefix' => 'part',
     'container' => 'section',
     'container_class' => 'part-container',
     'global_layout' => array(),
     'hide_options' => true
) );

I also think having some way to hide or disable options that you're registering this way would be necessary (the hide_options parameter above) -- otherwise you have the possibility of registering these options but you have a page where they are visible and editable to the user...so either the user edits them, and they are always changed back to how you registered them, or you allow them to edit the settings, and they potentially break everything.
