Calculate Pi using using Monte Carlo method

• pi_seq: Implements uses sequential calculations
• pi_con: Implements uses concurrency

Test

• Compile:

  c(pi_seq).
  c(pi_con).

• Run and compare elapsed time:

  pi_seq:run(23000000, 30).

  Pi: 3.1411624721233706
  Elapsed time: 65.489 seconds

  pi_con:run(23000000, 30).

  Pi: 3.1411339503854805
  Elapsed time: 19.501 seconds
