When matching for a single array, after a successful array element match, attempt to match all remaining elements. If the remaining elements could not be matched, reset the state and continue to the next entry in the array.

When matching an array, include the remaining arguments, otherwise, just match the single argument.
Calls superclass method

If any of the args are an array, handle backtracking such that if a later matcher fails, we roll back to the current matcher and proceed to the next entry in the array.
