Thanks for implementing the feature. We may want to consider 1 further change and 1 addition:

• add a boolean flag "execute_sequentially" (default set to false) in the ActionPlan class, such that, if for debugging reasons it is necessary to disable momentarily parallel executions, this can be done.
• move the SmartDaqApplication from appmodel to confmodel, since it seems to me the only class that is left on app model which contributes to the global basic schema. (DaqApplication and DaqModules are already in confmodel)

Unfortunately this is not currently possible due the hack used to register generate_modules methods with the SmartDaqApplication. The SmartDaqApplication has to be in the same package as its derived classes.

LGTM, but I'll update the configuration files according to the modifications in confmodel.
