Calculation of prime numbers using the algorithm of the sieve of Eratosthenes.
Prime is an application that implements three different functions about prime numbers:

Interval Prime: returns all prime numbers included in a given interval between two integer values;
Nearest Prime: returns the nearest prime numbers that define an interval in which the given number is included.
