+/**
+ *  Class CBTEngSrvState
+ *
+ *  This class implements the state machine for BTEng server.
+ *  The state machine is used for Bluetooth power on and power off operations.
+ *  A state machine is needed because the required operations for loading and 
+ *  initalizing all required services is time-consuming and would be too long 
+ *  to handle in one operation. It also includes asynchronous operations.
+ *  It is implemented in a separate class to make it easier extensible as well 
+ *  as to give a better overview of the state transitions and operations.
+ *
+ *  The state machine is initialized in state Init, and ends in state Idle. Any
+ *  state in between are temporary states (i.e. not accepting states).
+ *
