> Currently, {{CellPath}} exposes the interface with {{size()}} and {{get(int i)}}, although makes assertion that the passed size is {{0}}. 
> Also, there is a lot of code assuming that {{Path}} is always the size of {{1}} (which is true for now, of course, but will have to change during the transition to nested / composite paths).
> Examples of such code include: 
>   * {{ColumnDefinition}} path size check and comparator 
>   * {{Cell}} serialization / deserialization / calculating buffer size in {{CollectionType}} 
>   * {{CellPath}} copying 
>   * {{NativeCell}} code 
> Another problem is that CellPath currently does not contain a number of items in path. UPDATE: actually, it's possible to use the byte where we write {{HAS_MULTIPATH}} at the moment. It's a {{byte}}.
