FSMclass.h

// FSM.h
// Usage:
// 1. Declare a Finite state machine object : (code) FSMClass FSMSample
// 2. Create function as first state: (code) void FSMSampleState1(bool task)
// 2. Create function as second state: (code) void FSMSampleState2(bool task)
// 2.1 Take a look of the function sample
// 2. Initialize FSM in setup() function : (code)  FSMSample.init(FSMSampleState1);
// 3. Execute the FSM in run() function : FSMSample.run();
