now plots directly the input lp3. includes tests to validate prior behavior.

The following table contains the correct discharges of the input function for the west sac analytical flow-frequency function:

Frequency	Flow	Stage
0.5	202306	23.86
0.2	373981	27.38
0.1	508002	29.5
0.04	696277	31.66
0.02	848335	33.04
0.01	1009190	34.58
0.005	1179084	36.11
0.002	1417793	37.58

I see the discharges in the above table within inputFunction, it seems like inputFunction is not making it to the user interface
