/* SUMMARY:
* Main function
* INFO:
* [1] Start by init the watchdog, see wdt.h for macro options.
* [2] Init the current state to the entry state and the collection of return
* codes.
* [3] Setup the function pointer for the diffrent states.
* [4] Init the serial communication and enable global interrupts and
* init timer0.
* [5] Redirect the stdout and the stdin for serial streams through uart.
* MAIN LOOP:
* [1] Assign the function pointer a current state
* [2] Call the pointed function, and collect it's return code
* [3] Reset the watchdog
* [4] Check if the current state is exit and break(This will terminate)
* [5] If not, then move to the next state, declared in the transition table.
* [6] Repeat
