Default update time algorithm:
- Read initial runtime from the following sources
- kkit file
- annotations
- runtime dialog
- default to 100 second
- plotdt = runtime / 100 unless file specifies otherwise.
- simulationdt = plotdt. Ignore file if it is a kkit file.
- guiupdate time =
- runtime / 20. Run for 25% of runtime, ie, 5 updates.
- After 25% of runtime, Set update time = runtime / 10.
- Run for remainder of runtime
