def add leaf, attr, val
  if self.has_key? leaf
    self[leaf][attr] = val
  else
    self[leaf] = { attr => val }
  end
end

#attrs(leaves, attr) ⇒ AttrArray<Set>

Note:

If a genome is in the leaves array, but is not in the hash table, NO error will be raised. Rather that genome will be skipped. This is for cases in which not all genomes have attributes.

Returns the an AttrArray of Sets for the given genomes and attribute.

Raises:

  • (AbortIf::Exit) —

    if they leaf is present but doesn’t have the requested attr
