WheelOptions的设计问题

我觉得WheelOptions设计不合理，写死了只有3个wheelview，这样如果想进行扩展的话就很麻烦了（比如需要5个wheelview），能否进行改造可以不固定死wheelview的个数呢

Start by locating WheelOptions and tracing how the Android-PickerView options picker creates and uses its three wheel views. Identify the assumptions that prevent a variable number of wheel views, then define how existing three-wheel behavior should remain compatible. Done means callers can use more than three wheel views without the options picker being fixed to that count.
