 * \brief Set the Barcode Scanner application key to be used for this application
 *
 * Call this static method with the Scandit Barcode Scanner application key you downloaded 
 * from the Scandit website.  
 *
 * Setting the app key does not automatically activate the device. Device activations happen 
 * when a SBSBarcodePicker is instantiated for the first time. It is thus safe to set the 
 * app key at application start, irrespective if the user is going to scan barcodes or not.
 *
 * Note that currently it is not possible to change the app key after a picker has been 
 * instantiated. Only the app key set when the first picker is instantiated will be used. 
 * You will have to close the application and restart it before changing the app key.
 *
 * \param appKey the application key.
 * \since 4.7.0
