QMIMO-7 test what if our demo generator generates with some decimal places
QMIMO-7 add a new config # for # of decimal places in the dial sum Throughput numbers up top to round to, currently set to 0
QMIMO-7 clean up some guiCtrl comments & variables, & move the "MU Gain" decimal rounding out of code and in to the partials/gui.html since we can apparently just use https://docs.angularjs.org/api/ng/filter/number
