/*
	CompassRun.h
	Class designed as abstraction of a collection of binary files that represent the total data in a single
	Compass data run. It handles the user input (shift maps, file collection etc.) and creates a list of
	CompassFiles from which to draw data. It then draws data from these files, organizes them in time,
	and writes to a ROOT file for further processing.
