Axes definition

[stefanhahmann]

User story

As a user of Mastodon, it would make interpretation of data easier, if it was possible to define a coordinate system within the project.
Features that can be computed on the dataset may then be clearer to be communicated/interpreted (e.g. directions of cell divisions, directions of cell movements).
The coordinate system should reflect the orientation of the organism within the dataset.

Acceptance criteria

• Definition of 3 (orthogonal?) axes is possible via the user interface
  • Lateral - Lateral axis ("left" - "right", x-axis)
  • Ventral - Dorsal axis ("front" - "rear", y-axis)
  • Animal - Vegetal axis ("top" - "bottom", z-axis)

To be discussed

• Should there be one axes-definition per Tag-Set?
• User interaction to define axes within Mastodon
