Multiple scales

[ruiprieto]

I wonder if it would be possible to allow AragoJ to draw and use more than a single scale. Sometimes researchers draw two scales and obtain an average to minimize error. This is true for laser photogrammetry when researchers use three lasers, but also it is common in researchers measuring small objects from pictures including a scale.

One option would be to make the Scale by Reference module accept results from the Expressions Module.
