Description:: Function to find item in nested arrays and return a path to the first match.
In some cases findIf might be the better way of finding a nested element. It is a lot faster!
Execution:: call
Groups:: Arrays

Example 1:: private _array = [[1, 2], [3, 4]]; _path = [_array, 3] call BIS_fnc_findNestedElement; // expected result: [1, 0] // ((_array select 1) select 0) == 3
