class CudfCollectSet extends CudfAggregate

Spark handles NaN's equality by different way for non-nested float/double and float/double in nested types. When we use non-nested versions of floats and doubles, NaN values are considered unequal, but when we collect sets of nested versions, NaNs are considered equal on the CPU. So we set NaNEquality dynamically in CudfCollectSet and CudfMergeSets. Note that dataType is ArrayType(child.dataType) here.
