BasinFlow: Hydrograph Sum
Input Parameters:
name anything can go in here
Hyd1 the number of the first hydrograph in the input list
t1 the start time of the first hydrograph (using the same units as the hydrograph)
Hyd2 the number of the second hydrograph in the input list
t2 the start time of the second hydrograph (using the same units as the hydrograph)
route indicates whether this hydrograph will be routed

This is a summation of two given hydrographs.  If either of the hydrographs to be added is marked for routing, then the summation will occur after routing, using the routed discharge from the basin. If neither hydrograph is marked for routing, the summation will occur before routing, and the sum can be routed through the basin, or used in another hydrograph sum.
