Add Hydrographs

This function adds two hydrographs up and writes the new hydrograph to a file.

This command prompts you to select two hydrograph files. They can be either of Carlson style with the file extension of .hyd, or TR-20 style with the file extension of .h1. Then the program adds up the two set of data, the time interval is the smaller one of the two hydrographs. At the end, you are asked to specify a file for the output hydrograph.
