/*
	ShiftMap.h
	New class to act a go-between for timestamp shifts to channels. Takes in a
	formated file containing data for shifts and then stores them in an unordered_map.
	Key is a global compass channel (board#*16 + channel). Shifts in ps.

	Note: Timestamps are now shifted in binary conversion. This means that shifts *MUST*
	be stored as Long64_t types. No decimals!
