> A null value for a fixed length array can be handled with a bitset tacked on the end
of the array. If an element is set to null, then the bit at that index is set. Trailing nulls
are not stored and an attempt to access an array past the current size returns null.
> Current behavior,
> PBinaryArray - Throws an exception when a null is inserted.
> PBooleanArray - null is considered as false when a null is inserted.
> PCharArray - Throws an exception when a null is inserted.
> PDateArray - Throws an exception when a null is inserted.
> PDoubleArray - null is considered as 0.0 when a null is inserted.
> PFloatArray - null is considered as 0.0 when a null is inserted.
> PIntegerArray - null is considered as 0 when a null is inserted.
> PLongArray - null is considered as 0 when a null is inserted.
> PSmallIntArray - null is considered as 0 when a null is inserted.
> PTimeArray - Throws an exception when a null is inserted.
> PTimeStampArray - Throws an exception when a null is inserted.
> PTinyIntArray - null is considered as 0 when a null is inserted.
