v1.6.0

Validate MultiInstance Input as Array (for Data Input) or a Valid Number (for Cardinality)
If the Input is invalid the Activity will throw an Error
The error can be catch by a boundary event
Tests added to validate invalid Data Inputs and invalid Cardinalities.
When an empty data input is sent to a MultiInstance Task it will throw an INVALID_DATA_INPUT error, so the user could see problem and check it.
