Looks like it is not correct if input[id]<min. For example, input[id]=-1, min = 0, and max = 10, the result is -1, which is not expected.

While using GetAttrOrDefault() to get attribute for minimum/maximum values, it seems that ONNX has not yet supported double and float16 type as listed in AttributeProto_AttributeType. Once ONNX supports double and float16, we can add them as well.

* Moreover, properly handle default input situation
