+// Description:
+//  Insert a new entry into the call graph.  This entry says that the specified
+//  call site calls the specified function.
+//
+// Inputs:
+//  CS - The call site which calls the specified function.
+//  F  - The function which is called.  This is permitted to be NULL.  It is
+//       possible to have call sites that don't have any targets, and sometimes
+//       users just want to ensure that a call site has an entry within the
+//       call graph.
