Define parameters that may be used in model calculations (uses expressions)
add_item2(.data = NULL, input)A substituted expression to be evaluated by engine
Existing data
Items to define for the simulation as an expression (i.e., using )
DEPRECATED (old description): The functions to add/modify events/inputs use named vectors or lists. If chaining together add_item2, it will just append the expressions together in the order established.
If using pick_val_v, note it should be used with the deploy_env = TRUE argument so that add_item2 process it correctly.
