The SOM data structure - event handling

[borismarin]

Should the event descriptor be changed? I am not sure that its present form is the most convenient for template based codegen. Currently, a poor-man's event handler has been implemented in the test template matlab_euler. But it has some serious limitations:

1. not handling changes in dynamics
2. not handling multiple events (mostly due to difficulties in velocity (maybe only in airspeed) when handling nested sequences in #foreach loops.
   What would be the best way of describing multiple events? an array of "event" objects?

A better way of describing events is under experimentation in the eco-som branch
