+// Each object described by Fluid is one of these objects.  They
+// are all stored in a double-linked list.
+//
+// There is also a single "factory" instance of each type of this.
+// The method "make()" is called on this factory to create a new
+// instance of this object.  It could also have a "copy()" function,
+// but it was easier to implement this by using the file read/write
+// that is needed to save the setup anyways.
