* Checks if `n` is between `start` and up to, but not including, `end`. If |
|
* `end` is not specified, it's set to `start` with `start` then set to `0`. |
|
* If `start` is greater than `end` the params are swapped to support |
|
* negative ranges. |

* @param {number} number The number to check. |
