/**
* The CMStatusBarManager allows you to publish and remove CustomTiles within the
* Quick Settings Panel.
*
* <p>
* Each of the publish methods takes an int id parameter and optionally a
* {@link String} tag parameter, which may be {@code null}. These parameters
* are used to form a pair (tag, id), or ({@code null}, id) if tag is
* unspecified. This pair identifies this custom tile from your app to the
* system, so that pair should be unique within your app. If you call one
* of the publish methods with a (tag, id) pair that is currently active and
* a new set of custom tile parameters, it will be updated. For example,
* if you pass a new custom tile icon, the old icon in the panel will
* be replaced with the new one. This is also the same tag and id you pass
* to the {@link #removeTile(int)} or {@link #removeTile(String, int)} method to clear
* this custom tile.
*
* <p>
* To get the instance of this class, utilize CMStatusBarManager#getInstance(Context context)
