// usage
chance.prime()
chance.prime({ min: 1, max: 20 })

Return a prime number.

default range: 0 to 10000

  chance.prime();
  => 929

Can optionally provide min and max.

chance.prime({min: 1, max: 20});
=> 13

These are inclusive, so they are included in the range. This means chance.prime({min: 2, max: 5}); would return either 2, 3, or 5 or:

// Specific case
2 <= random number <= 5

// General case
min <= random number <= max
