> CategoryPath is supposed to be a simple object which holds a category path's
> components, and offers some utility methods that can be used during indexing
> and search.
> Currently, it exposes lots of methods which aren't used, unless by tests - I
> want to get rid of them. Also, the internal implementation manages 3 char[]
> for holding the path components, while I think it would have been simpler if
> it maintained a String[]. I'd like to explore that option too (the input is
> anyway String, so why copy char[]?).
> Ultimately, I'd like CategoryPath to be immutable. I was able to get rid most
> of the mutable methods. The ones that remain will probably go away when I
> move from char[] to String[]. Immuntability is important because in various
> places in the code we convert a CategoryPath back and forth to String, with
> TODOs to stop doing that if CP was immutable.
> Will attach a patch that covers the first step - get rid of unneeded methods
> and beginning to make it immutable.
> Perhaps this can be done in multiple commits?
