Thanks for your contribution @zentol. I've gone over the code and made some
inline comments. My main concern/question is actually the representation of
metric's type and hierarchy information. I think that encoding it in a string
and then re-parsing it on the receiver side to reconstruct the information is
rather fragile and error-prone especially wrt maintainability. Maybe you can
give me some background why you decided to do it so.
Apart from that, I think the code contains many tests, which I really like
:-)
