1.0.3

[1.0.3] 2021-02-28

Added

• [pconway.core.gameoflife.compute_cell_next_state] Compute the next state
  of a single cell.

Changed

• [pconway.render.play] and [pconway.clitools.gameoflife] Changed default
  alive_char from "o" to "." because it looks better.
• [setup.py] Read version number from pconway/version.py instead of
  separately definition.
• [pconway.tests.test_gameoflife.py] Changed random_matrix to accommodate
  recent changes.
• [pconway.core.gameoflife.mutation] Draw random number from np.random.binomial
  and use xor gate to perform mutation instead of using nested for-loops.
• [pconway.core.gameoflife.get_alive_neighbours] Use np.count_nonzero to count
  number of alive cells instead of using nested for-loops.
• [pconway.core.gameoflife.compute_next_state] Use np.vectorize and
  pconway.core.gameoflife.compute_cell_next_state (new) to compute
  next state of a matrix instead of using nested for-loops and statements.
• Put tests in the module instead.
• [pconway.render.play] Compute wait time efficiently by using time.sleep()

Fixed

• Typos in CHANGELOG.md
• Formatting according to PEP 8
