algorithmz 1.0.5

/// Returns the bubble sorted version of the input
///
/// This function takes a list as a reference and returns either the sorted list as a `Vec<i32>` or an error.
///
/// # Examples
///
/// Basic usage:
/// ```
/// let result = algorithmz::sorting::bubble_sort(&[2,1,4,3,5]).unwrap();
/// assert_eq!(result, [1,2,3,4,5]);
/// ```
///
/// With match statement:
/// ```
/// use algorithmz::sorting::bubble_sort;
/// let my_list = [1,3,2,5,4];
/// match bubble_sort(&my_list) {
///     Err(e) => eprintln!("The error was: {}", e),
///     Ok(nums) => println!("The result was: {:?}", nums),
/// }
/// ```
