question about clamp terms

[mah11]

In #33, @dianeoinglis asked for "FAO:0000061 fused clamp" to become is_a multicellular fungal structure, multicellular organism (now FAO:0002004), but the ontology structure is:

septate hypha
[is_a] clamp cell
-- [part_of] fused clamp
-- [part_of] unfused clamp

It doesn't make sense to have a multicellular structure be part_of a cell, which is what would be implied by adding the fused clamp is_a multicellular structure link.

So I wonder if the structure should be this instead?

septate hypha
[part_of] clamp cell
[is_a] fused clamp
[is_a] unfused clamp

i.e. fused and unfused are types of hyphal clamp, and a clamp cell is part of a hypha. Then the multicellular parent could be added to fused clamp with no nasty consequences.

If this sounds nuts, please bear with me - I'm very much still a beginner at learning fungal anatomy! I can make the changes if they do look OK.

In light of #48, I'm implementing the changes I suggested above. Reopen this, or start a new ticket, if anything looks amiss.
