Array: build dynamic list, iterate, find and remove items

ADD: Array Add (Target Array=MyArray, New Item=newElement). READ: Array Get (Target Array=MyArray, Index=i) → use 'Item' output. FIND: Array Contains (returns bool) or Array Find (returns index, -1 if not found). REMOVE by index: Array Remove (Target Array=MyArray, Index=i). REMOVE by value: Array Remove Item (Target Array=MyArray, Item=value). ITERATE: ForEachLoop(Array=MyArray) → 'Array Element' output is the current item. LENGTH: Array Length (returns int). Key: Array nodes operate on the array BY REFERENCE — always connect the array variable directly.
