Tidied and improced efficiency calculation.  Still work to do on errors.
Changed Crystal Efficiency array to one dimension to make it ewasier to plot (Num = (Clover *4)+Crystal).
Fixed bug causing seg fault during fitting.
Changed recommended compile line to -O0 as debugging with gdb is horrible while optimisation is on.  Revert once development complete.
TGraph of efficiency now plotted but looks horrible and canvas is messed up.  Fix this next.
Minor fixes
Titles printed to efficiency report
TGraphs of Crystal and Clover-add-back efficiency
Expected efficiency plotted as line on graph
Gate passed counter now as variable not counts in spectrum.  Also incremented in spectrum for reference when looking in the root file.
Titles and labels on graphs.
Few minor changes and fixes.
