public static ULongSpan extent(long min, int length) {

	}
Create a closed interval of unsigned longs having the given (unsigned) length

<p>
This operates the same as {@link #extent(long, int)}, but ensures the given length is treated
as an unsigned integer.

@param min
@param length
@return the span
@throws IllegalArgumentException if the upper endpoint would exceed {@link Domain#max()}
