* <ul>
* <li>The list of configured networks. The list can be viewed and updated,
* and attributes of individual entries can be modified.</li>
* <li>The currently active Wi-Fi network, if any. Connectivity can be
* established or torn down, and dynamic information about the state of

* <li>Results of access point scans, containing enough information to
* make decisions about what access point to connect to.</li>
* <li>It defines the names of various Intent actions that are broadcast
* upon any sort of change in Wi-Fi state.
* </ul>
* This is the API to use when performing Wi-Fi specific operations. To
