array class: Disable row method inherited from the vector class.
- array.row(i) would give i'th row in the underlying vector (!)
- Trigger compile error if a user applies the row method.
array: Allow single argument subset x(i) in any dimension.
- Recent commit enabled maps to work with matrices, but had the side effect to disable the same feature for arrays. With current commit this should be fixed.
