 Works like the bash `seq` command.

 * 1 parameter  (end) - will generate all counting integers between 1 and `end` inclusive.
 * 2 parameters (start, end) - will generate all counting integers between `start` and `end` inclusive incrementing or decrementing by 1.
 * 3 parameters (start, step, end) - will generate all counting integers between `start` and `end` inclusive incrementing or decrementing by `step`.
