SCSS nesting except the `&` operator isn't supported.

<code>
$scope = '.a, .b .c';

// $merged is '.a > .x, .a .y, .b .c > .x, .b .c .y'

),
array(

)
),
),
);
$meta = array(
'path'      => array( 'typography', 'fontFamilies' ),
'value_key' => 'fontFamily',
);
$values_by_slug = get_settings_values_by_slug();
// $values_by_slug === array(
//   'sans-serif' => '"Helvetica Neue", sans-serif',
//   'serif'      => 'Georgia, serif',
// );
</code>

param: array $settings Settings to process.

flatten_tree( $tree, $prefix = '', $token = '--' ) X-Ref

Given a tree, it creates a flattened one
by merging the keys and binding the leaf values
to the new keys.

It also transforms camelCase names into kebab-case

This is thought to be useful to generate
CSS Custom Properties from a tree,
although there's nothing in the implementation
of this function that requires that format.

For example, assuming the given prefix is '--wp'
and the token is '--', for this input tree:

{
'some/property': 'value',
'nestedProperty': {
'sub-property': 'value'
}
}

it'll return this output:
