C API -- Initialization

• Call fcm_open to obtain an FCM_FILE handle
• Obtain other handles from the FCM_FILE:
  • variable lists
  • operations
  • fields
• Call fcm_create to create an FCM_MODEL instance
• Other operations performed on the FCM_MODEL(s)
• fcm_destroy() to destroy an FCM_MODEL instance
• fcm_close() to free all resources associated with an FCM_FILE
• All FCM_MODELs created from the same FCM_FILE can use the same operation and variable list handles
