smawk-0.3.1

Version 0.3.1 (2021-01-30)

This release relaxes the bounds on the smawk_row_minima,
smawk_column_minima, and online_column_minima functions so that
they work on matrices containing floating point numbers.

• #55: Relax bounds to
  PartialOrd instead of Ord.
• #56: Update
  dependencies to their latest versions.
• #59: Give an example of
  what SMAWK does in the README.
