Modify the Application to Create Resources Dynamically

The util3 version of this example application calls sstore_data_attach() in the same way as in the util2 version and updates the statistic values in the same way. The stats structure is the same.

The util3 version of the ids array is the same as the util2 version except that the SSIDs are not statically listed in the application. In the util3 version, the ids array is built dynamically as resources are added.
