* ## User Configuration Library
*
* This library is an adapter for the UserConfigurationService of the shop's backend codebase. It will
* perform AJAX requests for getting/setting user config data that is a robust way to store information
* about a specific user.
*
*```js
* var options= {
* data: {
* userId: 1, // Current user ID
* configurationKey: 'recent_search_area', // Configuration key
* configurationValue: '', // Configuration value (only for posting)
* },
*
* onSuccess: function (data) {}, // Callback function, that will be executed on successful request,
* // contains the response as argument.
*
* onError: function (data) {}, // Callback function, that will be executed on failed request.
* }
*
* jse.libs.user_configuration_service.set(options); // Set values
*
* jse.libs.user_configuration_service.get(options); // Get values
* ```
