Gui element allows return of array.

[Cooldude2606]

Feature overview Name: Gui element returning an array TL;DR: The gui module should allow for the return of an array of elements which will be looped over for styling,

Details Allow for the return of an array, each value in the array should be a valid element, and checked to be valid, before being passed to the style callback. This array can then be returned to the caller, the caller should expect a table based on the element factory called.

Possible methods Test for a table return type, then iterate over it with ipairs.

Additional context Idea from #190 when returning an array was expected to be supported.
