[HOT] Tagging hut=yes

[chris zontine]

Greetings.

I was involved in mapping task 1034 and a fellow mapper mentioned they used the tag hut=yes in place of building=yes. I looked up the use of key hut[1] and apparently it is used but in very limited circumstances. 

The mapper said it was used to map a circular structure so I presume the usage was correct. Given the lack of general use what is the consensus on using this tag?
