handy function to setup z-index by name, if no schena is used then it will use the one from z-index settings

@function z-index($name, $schema:$z-index-map) {
    @if map-has-key($schema, $name) {
        @return map-get($schema, $name);
    } @else {
        @warn "The value #{$name} is not in the map '$z-index--map'";
        @return null;
    }
};
