+
+creates a set of four replicate units with a simple binding reaction each using a network file containing a multi-line comment.
+
+## tests
+
+- cps file reads well
+- gv file reads well
+- produces an expected warning about parameter scan
+- produces no other warning or error
+- four transport reactions are created
+- a reaction between units 3 and 4 is not created (it is inside a comment in the network file)
