When testing the speed and edgecases of the scripts it can be sometimes useful to clear the database.
This should be added to the CLI

After generating the primes, the current only method for recovering the primes is to read the entire database out.
A use most likely will not want this.

A method, or set of methods should be created to:

• Read the nth prime number
  This may have to include a change to the database write method, as currently this is not included

• The prime numbers between a range.

When searching for large prime numbers the array generated get extremely large. To the point that memory usage gets too large.
The method for finding primes should either:

• Chunk the arrays, completing them in turn, to restrict memory usage
  or

• After a certain point become a generator, like the original design

Currently, it takes longer to write the primes to DB than it does to calculate primes,
this is probably something to do with how the DB is being handled with the writes as a change from the old yield system

When running the code you get a very small number for the time of the search, it then hangs, as it completes the remaining work
