Diff since v0.2.4

v0.3.0 (June 6, 2025)

This release does not contain any breaking changes. But the
following new Lefschetz complex functionality and examples
have been added since release 0.2.0:

• Added lefschetz_interior to determine the interior of a Lefschetz
  complex subset, if the Lefschetz complex is interpreted as a finite
  topological space.
• Added lefschetz_topboundary to determine the topological boundary
  in the above setting.
• Added example_dunce_chaos. It constructs a Forman vector field
  on a minimal representation of the dunce hat which has a chaotic
  isolated invariant set with trivial Conley index.
• Added example_torsion_chaos. It constructs a Forman vector field
  on a simplicial complex with torsion which has a chaotic isolated
  invariant set with trivial Conley index, for certain values of the
  field characteristic. In addition, an associated gradient vector
  field has large entries in the connection matrix.

In addition, and in anticipation of future extensions, more sparse
matrix functions have been added:

• The functions sparse_add, sparse_subtract, and sparse_scale
  perform sparse matrix addition, subtraction, and scalar multiplication.
  All of these functions can also be involved using the operators
  +, -, and *, respectively.
• A new function sparse_nonzero_count determines the number of
  nonzero entries of a sparse matrix.
