## Detailed Description

template<class SimplexTree>
class Gudhi::Simplex_tree_optimized_cofaces_rooted_subtrees_simplex_iterator< SimplexTree >::is_coface

Predicate to check whether an input SimplexTree::Node represents a coface of a simplex simp_, stored as a std::vector of SimplexTree::Vertex_handle sorted in decreasing Vertex_handle order.

Given a SimplexHandle in a simplex tree cpx_, traverses the tree upwards to find the sequence of Vertex_handle of simp_ as a subsequence of labels encountered. Does not test sh itself. Used for filter_iterator in the optimized algorithm for star_simplex_range.
