*** Simplex tree construction with Z/2Z coefficients on weighted graph Klein bottle file:

./Simplex_tree_example_from_cliques_of_graph ../../../data/points/Klein_bottle_complex.txt 2
Insert the 1-skeleton in the simplex tree in 0 s. 
Expand the simplex tree in 0 s. 
Information of the Simplex Tree: 
  Number of vertices = 10   Number of simplices = 82

with Z/3Z coefficients:

./Simplex_tree_example_from_cliques_of_graph ../../../data/points/Klein_bottle_complex.txt 3

Insert the 1-skeleton in the simplex tree in 0 s.
Expand the simplex tree in 0 s.
Information of the Simplex Tree:
  Number of vertices = 10   Number of simplices = 106
