Title: Added optional $step param to range method (function)

The $step param defaults to 1 but allows for use of PHP's optional third param which increments the array by the specified integer.
```
range(15, 60, 15); //15, 30, 45, 60

Note: on my last pull request I didn't actually add the $step param to the range() function. It is included here now.
