/**
* @brief simple timer
*
* Simple and memory saving implementation. Should handle timer register wrap around well.
* Maximum period is at least 49 days. Resolution is one millisecond. To save memory, doesn't store timer period.
* If you wish timer which is storing period, derive from this. If you need time intervals smaller than 65 seconds
* consider implementing timer with smaller underlying type.
