Notes and Changes:
v4 - updated MC numbers, adding spreadsheet with histograms from MC analysis. Also added some details about the coating optimization and the assumed dispersion relation.
v5 - updated calculations with dispersion from Ramin, changed constraints on layer thickness in particle swarm optimization
v6 - updated calculation based on new dispersion from Ramin.
v7 - fixed bug in code related to taking into account dispersion properly
v8 - slightly reduced sensitivity to assumed parameters for both coatings
v9 - specified Substrate to be Corning 7980 HPFS UV-0F grade, fixed axes labels in MC study plots.
