Device Information Properties

Device Information Properties allow us to see what the Module is doing on the network. This includes:
 * Device State: indicates what the Module is doing. On the Coordinator it should be "DEV_ZB_COORD" once the device establishes the network. It's good to periodically poll the device state and verify it in your application.
 * MAC Address
 * Short Address
 * Parent Short Address: this is which device is this device's "parent". To send messages to the coordinator, this device will have to send them to the parent first. Coordinator will have a parent short address of 0.
 * Parent MAC Address: this is the 64 bit IEEE address of this device's parent.
 * RF Channel
 * Personal Area Network Identifier
 * Extended PAN ID: This is the 64 bit IEEE address of the coordinator of this network.
