- Order elements top to bottom/left to right/right to left etc.

- *******
-
- element properties
-
- stacking-dir -- stack contents of elements in which direction ?
-
- align-dir -- Which side to align? -1: left side, 0: centered (around
- center_l_ if not nil, or around center of width), 1: right side
-
- threshold -- (cons MIN MAX), where MIN and MAX are dimensions in
- staffspace
-
- alignment-done -- boolean to administrate whether we've done the alignment already (to ensure that the process is done only once)
-
- group-center-element -- element which will be at the center of the group
- after aligning (when using Align_interface::center_on_element)
-
- elements -- to be aligned elements
-
- axes -- list of axis numbers. Should contain only one number.
-
- *******
-
- Reads the following from its elements
-
-
- minimum-space -- (cons LEFT RIGHT)
-
- extra-space -- (cons LEFT RIGHT)
