UML Sequence Diagram

I recently had to come up to speed on some new code, so I decided to use a UML sequence diagram to help me digest the code as well as to create some documentation.  If you ever need to create a sequence diagram, here is an Adobe Illustrator template that I used.  For such documentation, Google Drawings or Visio is typically a better choice than Adobe Illustrator, but if you want to improve your advanced diagramming skills, Adobe Illustrator is the way to go.
