Roll Class

Roll Constructor expects a table of the roll's name (string), number (int), and targets (set)
Rolls save a table for each roll instance in Roll History. rollTargets inside this history are maintained so that names are not repeated 
		ex: { [1]={rollNum=3,rollTargets={Ejiin,Sudox}},[2]={rollNum=4,rollTargets={Flippant}} }
This makes it easier to display roll summaries
