Progress: Leakage pdfs, I have added the plotting function.  Things to address soon: 1) The plots are not normalized correctly: you should not have probabilities of 10.  2) I don't think there is any checking of whether the method was run/whether you want to plot the pdf of the leakage results.  It may be nice to give these a checking function in the input checking subroutine.  3) Running all methods functions just fine, but running only the atomic mix functions segfaults in 'MCLeakage_pdfbinprint'.  Fix this and ensure other combinations do not segfault.
