public static TensorAddress of(int label) {
        return new TensorAddressAny1(LabelCache.GLOBAL.getOrCreateLabel(sanitize(label)));
    }
Parent of tensor address family centered around each dimension as int.
A positive number represents a numeric index usable as a direct addressing.
- 1 is representing an invalid/null address
Other negative numbers are an enumeration maintained in {@link Label}
