This Erlang module implements a function that returns the elements of a 2D matrix (list of lists) in a spiral order. The spiral order starts from the top-left corner and proceeds in a spiral pattern, moving right across the top row, down the right column, left across the bottom row, and up the left column, and continues until all elements are traversed.
