  FUNCTION DESCRIPTION:
    Will find a layer by looking for name and type
    
  INPUT:
    nameInput (String) = The name of the layer you're looking for
    OR
    nameInput (Array) = Multiple names to add to the results (can be used as alternative spelling)
    type (String) = "ArtLayer" or "LayerSet" or "Any"
    
  OUTPUT:
    Returns the matching layer as an object
    If multiple layers were found - returns an array of those layers
    Returns Null if no layer was found
    
  NOTE:
    None
