     "Playing around with the input for an individual system gives us some understanding of which parameters affect the formation of black hole systems, but, as mentioned in the introduction, this is nto the most appropriate way to find many such systems. We want to make use of the Population utilities, and set up custom logging and a parse function.\n",
