[louiskhchan]

Currently, Mockoon has array helpers like filter and slice. It would be ideal if a sort helper could be added.

We discussed a bit with @ajatkj and propose the following implementation with two helpers:

• {{sort 'asc|desc'}} for arrays of strings and numbers.
• {{sortBy 'keyname' 'asc|desc'}} for arrays of objects.
