Constructor for ClusterIso Class the coneSize is taken in as an integer multiple of .1 ie if you want R=.2 pass 2
Contructor takes the argument of the class name, the minimum eT of the clusters which defaults to 0, and the isolation cone size which defaults to 0.3.

Function to get correct tower eta
Each calorimeter tower's eta is calculated using the vertex (0,0,0) which is incorrect in many collisions. This function uses geometry to find a given tower's eta using the correct vertex.

Calculates isolation energy for all electromagnetic calorimeter clusters over the specified eT cut.
For each cluster in the EMCal this iterates through all of the towers in each calorimeter, if the towers are within the isolation cone their energy is added to the sum of isolation energy. Finally subtract the cluster energy from the sum
If there event is embedded in Au+Au or another larger background we want to get isolation energy from the towers with a subtracted background. This first section looks at those towers instead of the original objects which include the background. NOTE: that during the background event subtraction the EMCal towers are grouped together so we have to use the inner HCal geometry.
This second section repeats the isolation calculation without any background subtraction
