Description
We add a method to Polyhedron_base
and CombinatorialPolyhedron
, which wraps flag_f_polynomial
of FiniteLatticePoset
so that flag_f_vector(1,3)
returns the f_{1,3}.

A few things:
 In the documentation,
(number of faces of each dimension)
should not say the same as the fvector but say what the flag fvector counts.  Remove the backticks and add dash (in combinatorial polyhedron too):
 Return the `flag_f_vector`. + Return the flag fvector.
 For each `1 < i_0 < \dots < i_n < d` the `flag_f_vector` + For each `1 < i_0 < \dots < i_n < d` the flag fvector
 Backticks missing here (in combinatorial polyhedron file too):
 counts the number of flags `F_0 \subset \dots \subset F_n + counts the number of flags `F_0 \subset \dots \subset F_n`
 Spelling (in combinatorial polyhedron too):
  a dictionary, if no arguments where given    an Integer, if arguments where given +  a dictionary, if no arguments were given + +  an Integer, if arguments were given
