getInstance

Factory method that performs validation and copies the parameter array.

Parameters: closures the closures to chain, copied, no nulls

Returns: the chained closure

Throws: IllegalArgumentException if the closures array is null IllegalArgumentException if any closure in the array is null

getInstance

Create a new Closure that calls each closure in turn, passing the result into the next closure. The ordering is that of the iterator() method on the collection.
