Description

----------

A command line applicaton which accepts an integer as a paramater which displays a multiplication table of prime numbers, up to and including the given integer. 

Usage

-----

Clone the repo.

Run ```bundle install```

To run the program, run ```bin/prime_time```

By default the app will return a 10 column and row times table of prime numbers. However, by appending ```--count ``` and replacing `````` with an integer of your choosing, you can make the table as large or as small as you like. 

In order to check tests and functionality, run ```rspec spec```

Examples

---

Standard output (```bin/prime_time```) with no parameters given should look like this:

```

   |  2|  3|  5|  7| 11| 13| 17| 19| 23| 29|

  2|  4|  6| 10| 14| 22| 26| 34| 38| 46| 58|
