-This is a test for the API function that changes a link's type.
-Two links in Net1.inp are changed: Pipe 113 is reversed with a CV added
-and Pipe 121 is changed to a 100 psi PRV. After running the revised model,
-at hour 0 the flow in Pipe 113 should be zero and the pressure at node 31
-of the PRV 121 should be 100.
