Display all conditions on screen

[carrascomj]

Implementation

Spawm a new X-axis Component per node set of hist-like geoms which contains information about the size, calculated based on the arrow direction; and the anchor space, the x-limits of the data across conditions.

Allow for a All selectable condition (default).

Further considerations

For usability, this will require a rework in the drag-and-rotate interaction (maybe with a bounding box?) system and the map saving, now saving axes instead of histograms.
