Primespiral is a function to explore the distribution of prime numbers arranged into a spiral pattern.
The well-known Ulam spiral and the variant developed by Robert Sacks,
the Sacks spiral, show interesting geometric patterns in the positions of primes.
t - is an integer number. The spiral will be plotted between 0 and t
If t is omitted, it will be set to 3571 (between 0 and 3571
there are 500 prime numbers).
primesout - the primes of the choosed family, between 0 and t.
The function will ask if you want to use the Ulam, Sacks, Vogel or Archimede spiral.
Then it will ask if you want to highlight a particular prime family.
The primes of the family you choosed between 0 and t
