Functions

func IsForkTransition 

func IsForkTransition(fork *uint64, parent *uint64, current uint64) bool

IsForkTransition returns true if `fork` activates during the transition from `parent` to `current`. Taking `parent` as a pointer allows for us to pass nil when checking forks that activate during genesis. Note: `parent` and `current` can be either both timestamp values, or both block number values, since this function works for both block number and timestamp activated forks.
