NEW: Updated for R2015a.
NEW: Example demonstrating the Reorder Point method.

The library consists of a top-level SimEvents library called

se4_process.slx,

eight sub-libraries:

1. se4_batching.slx,
2. se4_conveyor.slx,
3. se4_math.slx,
4. se4_utilities.slx,
5. se4_DateTime.slx,
6. se4_subsystem.slx
7. se4_examples.slx,
8. se4_test.slx,

five test bench models:

1. test_accumulate.slx,
2. test_batching.slx,
3. test_conveyor.slx,
4. test_DateTime_days.slx, and
5. test_DateTime_minutes.slx.

and three example models:

1. Goldratt_Dice.slx
2. Job_Shop.slx
3. Reorder_Point.slx
