a very simple efficient state machine in C

added howto document by using dot(graphviz)

A few comments:

  • keep local global variables hidden for outside by : static int myLocalVar;
  • consider if it is wise to implement memory in a state: local var like static int IWillKeepValue;
  • consider if more states is better than complex code in state(s)
  • it is possible to track within the main "while (1)"
