// This class stores the information of a single element of an address list
// These things consist of three entries: The type, which can be IN=1 or OUT=2,
// indicated by a '<' or '>' in the schedule. Then there is the actual address
// in memory which is a simple integer in our language. And last, there is the
// size of data referenced by this address which is an integer and denotes the
// size in bytes.
