The authors code examples go back and forth between spelled correctly and not spelled correctly so I'm not quite sure what hes advocating. Figure 13 is especially hilarious.
pload: I have no idea what 'p' is
qload: I have no idea what 'q' is
numBuses: should have been busCount probably
numTransLines: what is 'trans' ?
systemName: ah a good one!
gens: should have been generators but even in that case its basically useless. I already know its a vector of Generators, what is its higher level function?
transLines and buses: same as 'gens', just a name of the type.
