Refactored parts setTimeStepList.cc to make it more readable.
If the number of outputs is set to 0, there are no outputs, regardless of the output type. Previously this was ignored for lists; however, the user should ignore the parameter and let PRISMS-PF use the default value of 10.
Added assertions for N_PER_DECADE so that the total increments is greater than 1.
The log spacing is working as intended. Note that our log spacing does not correspond to something like MATLAB's logspace because they begin at 10^0 while we start at 0.
