/**
* Provides convenience methods for in-app billing. You can create one instance of this
* class for your application and use it to process in-app billing operations.
* It provides synchronous (blocking) and asynchronous (non-blocking) methods for
* many common in-app billing operations, as well as automatic signature
* verification.
*
* After instantiating, you must perform setup in order to start using the object.
* To perform setup, call the {@link #startSetup} method and provide a listener;
* that listener will be notified when setup is complete, after which (and not before)
* you may call other methods.
*
* After setup is complete, you will typically want to request an inventory of owned
* items and subscriptions. See {@link #queryInventory}, {@link #queryInventoryAsync}
* and related methods.
*
* When you are done with this object, don't forget to call {@link #dispose}
* to ensure proper cleanup. This object holds a binding to the in-app billing
* service, which will leak unless you dispose of it correctly. If you created
* the object on an Activity's onCreate method, then the recommended
* place to dispose of it is the Activity's onDestroy method.
*
* A note about threading: When using this object from a background thread, you may
* call the blocking versions of methods; when using from a UI thread, call
* only the asynchronous versions and handle the results via callbacks.
* Also, notice that you can only call one asynchronous operation at a time;
* attempting to start a second asynchronous operation while the first one
* has not yet completed will result in an exception being thrown.
*
