Compass::SassExtensions::Functions::Sprites#sprite_map

Creates a Compass::SassExtensions::Sprites::SpriteMap object. A sprite map, when used in a property is the same
as calling sprite-url. So the following background properties are equivalent:

    $icons: sprite-map("icons/*.png");
    background: sprite-url($icons) no-repeat;
    background: $icons no-repeat;

The sprite map object will generate the sprite map image, if necessary,
the first time it is converted to a url. Simply constructing it has no side-effects.
