ArrayCreatingInputMerger

class ArrayCreatingInputMerger : InputMerger

An InputMerger that attempts to merge the inputs, creating arrays when necessary. For each input, we look at each key:

• If this is the first time we encountered the key:

• If it's an array, put it in the output

• If it's a primitive, turn it into a size 1 array and put it in the output

• Else (we have encountered the key before):

• If the value type matches the old value type:

• If they are arrays, concatenate them

• If they are primitives, turn them into a size 2 array

• Else if one is an array and the other is a primitive of that type: * Make a longer array and concatenate them

• Else throw an IllegalArgumentException because the types don't match.

If a value by a key is null, it is considered to have type String, because it is the only nullable typed allowed in Data.
