It's a class for an associative array data structure. All it does really is map two arrays to each other.

{key1, key2}
{value1, value2}

all array.item(key1) does is find the index of key1 (in this case zero) and return the value at the same index (value1).

I provided functionality for looping through which is in the example usage.
