nRF5 SDK for Mesh(八) Exploring Mesh APIs using light switch example，使用灯开关案例探索BLE mesh 的APIS

The light switch example is meant to showcase the APIs for the provisioner and provisionee roles and how a simple Bluetooth Mesh network may be set up and configured. The network consists of one static provisioner (that configures a network in a fixed predefined way), one light switch (that implements a Simple OnOff client), and one or more light bulbs (that implement Simple OnOff servers).
