  * GULP TASKS
- * 
+ *
  * Gulp tasks in Gulp 4.0 are a description of a series of functions.
  * The functions are all above and are easier to maintain individually
- * 
+ *
  * Each "task" is then responsible for wiring up the dep trees itself,
  * because of this you have a finer degree of control of the ordering
  * of your tasks **and** you can optimize the parallelization of each
