  10 Specifications of Phylomemy export format.
  11
  12 Phylomemy can be described as a Temporal Graph with different scale of
  13 granularity of group of ngrams (terms and multi-terms).
  14
  15 The main type is Phylo which is synonym of Phylomemy (only difference is
  16 the number of chars).
