This function uses the Sieve of Eratosthenes to find all the primes less than or equal to a given integer.

1 | ```
primesieve(sieved, unsieved)
``` |

`sieved` |
Identified primes (empty vector for initialization) |

`unsieved` |
Candidate integers |

The function assumes that `unsieved` is a vector of positive integers.

Returns a vector of primes sieved (selected) from the input vector.
