Notice

support two modes:

1. parallel: such as time picker, wheels have no connection with each other

2. cascade: such as date picker, address picker .etc, when front wheel changed, the behind wheels will all be reset

parallel:

• single wheel:

	pickerData = [1,2,3,4];
	selectedValue = 3;

• two or more wheel:

	pickerData = [
		[1,2,3,4],
		[5,6,7,8],
		...
	];
	selectedValue = [1, 5];

cascade:

• two wheel

    pickerData = [
        {
            a: [1, 2, 3, 4]
        },
        {
            b: [5, 6, 7, 8]
        },
        ...
    ];
    selectedValue = ['a', 2];

• three wheel

    pickerData = [
        {
            a: [
                {
                    a1: [1, 2, 3, 4]
                },
                {
                    a2: [5, 6, 7, 8]
                },
                {
                    a3: [9, 10, 11, 12]
                }
            ]
        },
        {
            b: [
                {
                    b1: [11, 22, 33, 44]
                },
                {
                    b2: [55, 66, 77, 88]
                },
                {
                    b3: [99, 1010, 1111, 1212]
                }
            ]

                },
